Police have arrested the man accused of sexually assaulting a 13-year-old boy earlier this week in Brownsville.

The NYPD arrested Brooklyn native Christopher Fiesco, 32, around 5 a.m. Friday.

Fiesco is charged with luring a child to commit a felony, criminal sex act and sexual contact with an individual less than 14 years old.

Police reported a man approached the 13-year-old Monday afternoon and began chatting about video games. The suspect then allegedly pulled out a knife on the boy and led him to an apartment where police believe he sexually assaulted the teen.
