A missing Brooklyn boy was found Monday, almost a week after he disappeared after returning from school.
Police say 11-year-old Kareem Granton was last seen on Wednesday.
Relatives say after school, he went to play video games with a friend who lives two floors above him at the Unity Plaza Houses in East New York.
His friend says Kareem left the apartment several hours later, but he never arrived home.
Kareem said that afterwards he ran away and spent days going to a mall and riding and sleeping on trains, though he wasn't always alone.
He was found riding a southbound 4 train by himself in Union Square.
"They went to the Barclays Mall, him and his friend got separated, and he couldn't find his way back," said NYPD Officer Dennis Grimm.
"I just had a tantrum in the moment, a type of anger problem, so I just wanted to express it in a different way," Granton said.
"I was happy, I wanted to be jumping like I won a million dollars, that my son was back," said the boy's mother, Precious Granton. "They said that my son said his name is Kareem, so he know his name that was him."
"We're here to say that this is a happy ending unlike other circumstances that we've dealt with in the past," said Community Activist Tony Herbert.
