A suspected mystery shooter who fired twice at a luxury Manhattan apartment building has turned himself in, police say.

The 22-year-old Farris Koroma walked into the police station with his attorney early on Friday morning and said he was the suspect caught on surveillance footage.

According to police, the suspect fired in both incidents from across the East River on Roosevelt Island.

Though windows on two floors were shattered but no injuries were reported.

Koroma faces criminal possession of a weapon, reckless endangerment, and criminal mischief charges.

According to a report by a local news outlet, he is not believed to have a criminal record.

The two shootings took place in the span of fewer than 48 hours, which began on August 14.

People told BBC that in both incidents, victims were awoken to the sound of bullets crashing through the windows of their apartments at One East River Place.

During a weeklong manhunt, the New York Police Department (NYPD) released footage of the suspected gunman and a woman walking along the river.

Police said the woman is just a witness and will not be arrested.

Koroma was moved to a central booking office on Friday. According to ABC 7, he is scheduled to appear before a judge later on Friday.

The victims were awoken by the sound of their glass windows breaking, in both incidents.

Bullet fragments were later recovered by police from the flats, which are on the 14th and 32nd floors of the 50-storey rental building.
