Israeli police have raided a family-run Palestinian bookshop in East Jerusalem for the second time in a month, confiscating more than 50 books and briefly arresting the owner.
The Educational Bookshop is a literary haven in the city selling a wide variety of titles discussing the Israeli-Palestinian relationship and Middle East culture.
Supporters of the Muna family, who run the store, have said it is being targeted as part of a crackdown on freedom of speech and expression by Israeli authorities.
On Tuesday morning Israel Police arrived at the store, not far from the walls of Jerusalem's Old City, and arrested its owner Imad Muna.
Police seized books from the shelves, going so far as to ask Imad's wife Najwa for plastic bags to help carry what they had claimed was evidence against him.
CCTV shows almost a dozen police searching the store, with one heavily armed officer standing guard on the street outside.
Mr Muna's brother Murad said police did not present a search warrant as they entered the store and ordered it to close.
"Najwa tried to go to the bathroom and they pointed their guns at her and started yelling at her, 'Where are you going and what are you doing,'" Murad told the ABC.
"Then she said she was going to the bathroom.
"They came, opened the door, there was a picture on the wall, they threw the picture on the ground, then they turned on the light and said, 'now, go in.'"
Israel Police confirmed Imad Muna was released shortly after being taken into custody.
"The Israel Police received a report from a caller who stated that he had observed books containing inciting content at a bookstore in Jerusalem," police told the ABC in a statement.
"Upon arrival at the scene, officers seized three books and temporarily detained an individual present at the location to verify his identity and the details of the store.
"Following the verification process, the individual was released.
"The police have initiated a review of the books, and based on the findings, a determination will be made on whether to refer the matter to the State Attorney's Office for further investigation into the suspected sale of inciting materials."
Among the books seized but returned are titles by British street artist Banksy, American author Noam Chomsky and Israeli historian Ilan Pappé.
Two of the three books police kept are Footnotes in Gaza, by journalist and cartoonist Joe Sacco and Israel and the Clash of Civilisation, by British writer Jonathan Cook.
CCTV captures man believed to have tipped off police
Murad told the ABC the family believed they knew who had called the police, and that the man could be seen on CCTV visiting the store about an hour before the officers arrived.
"He came to Najwa half an hour before [the police arrived] and opened the book of Joe Sacco, 'Footnotes in Gaza'," Murad said.
"And he saw a picture of children with blood on their hands, and he asked Najwa what was this picture.
"She said to him 'this is a picture of when they slaughter a lamb following the construction of a new home and people put the blood on their hands and then paint the walls.' It's a ritual/tradition that people do in the world.'
"And then he said to her, 'Now I understand why they raided you the last time.' And then he left."
Murad said the man spoke English and was carrying a camera with a long lens.
Second raid by Israeli police
In February Mahmoud and Ahmed Muna, Imad's brother and son, were arrested and charged with breaching the peace by selling books with Palestinian themes and imagery.
One of the books sparking concern was a children's colouring in book titled 'From the River to the Sea', which is a Palestinian resistance phrase.
After two nights in custody, the pair were released.
Ahmed described the latest raid as "heartbreaking."
"For me this time it was even harder than last time when I was arrested," he said.
"But this time, I had to see my mum and dad being humiliated by them.
"They were only two police, and then two more arrived, and then two more undercover, and then two more undercover.
"They made a whole scene, you know? They closed the road, they drover against the traffic. They were coming as if it were an emergency.
"They came in cars from all corners, and then more undercover police came and more undercover police came. We ended up with 10 people in the shop."
He said it was a concerning development.
"We live in a country where police officers have freedom to do whatever the heck they like," Ahmed said.
"In a country where freedom of speech is being limited.
"Where police come and search bookshops and cultural institutions"
The first raid in February prompted outcry from members of the expat community in Jerusalem, labelling it as an attack on freedom of speech, and a number of foreign diplomats had packed into one of the city's small courtrooms to show their support for the family and watch the court proceedings unfold.
Israel's State Prosecutor had criticised police's actions in the weeks after the bungled raid, saying officers had not requested an investigation be launched into alleged incitement offences before the arrests were made — something required under Israeli law.
Local media reported the prosecutor's office had told police it should not happen again.
