A man is facing charges for his role in a Norwalk robbery where a juvenile was threatened with a knife, police say.

On July 12, police were called to Veteran's Park around 11:30 p.m. for a robbery.

A juvenile informed police he had arranged a meeting through Snapchat to sell several high-value items. When the victim arrived, he was approached by three men.

One of the men had a knife and robbed the victim, according to authorities. Following the incident, all three men left the area.

Mario Osorio-Lopez was arrested Wednesday.

He was charged with robbery, larceny, two counts of risk of injury to a minor and conspiracy to commit robbery.

Osorio-Lopez is scheduled to appear in court later this month.

Police say more arrests are expected in this case.
