Chloe Moretz has reportedly reported a person offering her cookies to the authorities

A law enforcement source told TMZ, the 'The 5th Wave' star was inside her home at the time and claimed the supposed trader was around 18 years old.

However, the police were unable to speak to the seller and ask him about his whereabouts because he made a swift getaway on his skateboard.

But it is believed the uninvited visitor had been desperately asking residents in the area if they had any details on where Chloe lived prior to pitching the goods sale to her, which reportedly caused one neighbour to question him about his interest in the star.

The threat management team within the Los Angeles Police Department (LAPD) are believed to be investigating the incident.

Meanwhile, the 'Neighbors 2: Sorority Rising' star has vowed to remain focused and to surround herself with positive people so not to get distracted by "all the trash" around her.

Speaking previously, she said: "Keep good people around you because positivity begets positivity. I learned that the hard way. Just try to keep your head above the water and don't get caught up in all the trash."

And Chloe believes she doesn't need to have everything figured out as a young woman but she has learned to ask for help if she needs it.

She said: "This year especially, I had to realise that it's OK to ask for help - it's OK to not know. As a young woman you feel like you really need to have everything figured out - but it's all right to say, 'I don't know. I have absolutely no idea.'"
