Police have arrested a man they say sexually assaulted a 13-year-old girl after tying her and a 13-year-old boy up at knifepoint in a Queens park, officials said Tuesday.

Christian Inga, 25, of Corona, was taken into custody early Tuesday morning in connection with the attack in Kissena Corridor Park, NYPD officials said at a news briefing.

Inga faces charges of first-degree rape, first-degree sex abuse, first-degree robbery, second-degree kidnapping, first-degree menacing, first-degree unlawful imprisonment, fourth-degree criminal possession of a weapon and acting in a manner injurious to a child, the NYPD said. 

Police said the two teens were walking in the park near Kalmia Avenue and Colden Street around 3:30 p.m. on June 13 when Inga approached them and demanded they follow him into the woods.

When the teens refused, Inga pulled out a machete-style knife and forced them to follow him into a secluded area in the park, police said. 

Inga tied the teens’ wrists together with a shoelace and sexually assaulted the girl before fleeing with the teens’ cellphones, according to police. The teens were taken to a nearby hospital in stable condition, the NYPD said.

Police arrested Inga after several 911 callers reported spotting him at the intersection of 108th and Waldron streets in Corona, NYPD Chief of Detectives Joseph Kenny said at Tuesday’s briefing.

When police arrived at the scene, they found Inga detained by a group of neighborhood residents, Kenny said.

“At the time, the community was trying to hold the perpetrator waiting for the police,” he said. “He fought with them, and the community still managed to hold onto him until we got there.”

Inga was initially taken to Elmhurst Hospital Center, where he was treated for minor injuries, Kenny said. As of Tuesday afternoon, he was being held at the 112th Precinct in Forest Hills. 

Kenny said Inga “made statements after waiving Miranda rights where he indicated that he has a drug problem, that he found the knife that he used to threaten the two teens, that this was the first time he had ever done anything like this.”

“He ID[ed] himself in video that was shown to him,” Kenny said, adding that Inga had no prior arrest history in New York City, but three prior encounters with the NYPD, and had one prior arrest in Texas.

The NYPD received “numerous tips from Queens residents” before the arrest “that gave us the perpetrator’s name, his Facebook account, which gave us pictures of him wearing the clothing he was wearing the same day that he committed the crime, as well as pictures of with that distinguishable tattoo on his chest and matching clothing,” Kenny said.

At the briefing, NYPD Commissioner Edward Caban praised the public’s role in the investigation.

“There is no greater force multiplied than the eyes and ears of the engaged, fully involved public. This is exactly what we mean when we talk about public safety [being] a shared responsibility,” Caban said. “And the past three days prove to the world, again, that the people of this city can come together and get the job done like no one else.”

Inga’s attorney information wasn’t immediately available Tuesday.
