An MS-13 gang member accused of stabbing two women and sexually assaulting a 2-year-old girl in a New York City suburb had a string of arrests to his name, on top of his four deportations.

Tommy Alvarado-Ventura, 31, is suspected of assaulting the child between Tuesday and early Wednesday while the girl’s mother was at work. He lived on Long Island and had been deported from the U.S. four times.

Alvarado-Ventura had a history of prior arrests for offenses including drunken driving, disorderly conduct, assault, false impersonation and contempt of court, according to police. Details on those arrests were not immediately released; police said their investigation is ongoing.

Authorities said Alvarado-Ventura had been with the child before going to a nearby bar, where he argued with a 24-year-old woman over a marijuana deal and then stabbed her in the parking lot. The woman suffered a collapsed lung, police said.

He then returned to the apartment where the child lived, police said. When the child's mother returned home from work at about 4:15 a.m. Wednesday, she discovered injuries to her child and argued with Alvarado-Ventura. During that argument, he beat and stabbed the woman, police said.

After the stabbing, the girlfriend ran to another woman who lived in the apartment, WNBC reported.

That woman told the station in Spanish that the girlfriend came to her frantic and bleeding and that the 2-year-old was covered in bruises.

She was being treated for stab wounds, according to the station.

Nassau County Police Commissioner Thomas Krumpter accused Alvarado-Ventura of committing “probably the most heinous criminal act I've ever seen” in 28 years in law enforcement.

“It really is nauseating,” he told a news conference Thursday.

Alvarado-Ventura was deported to El Salvador four times between 2006 and 2011, police said. It was not known when he returned to the United States.

He has been accused of attempted murder, predatory child sexual assault, assault and weapons possession. He faces life in prison, if convicted.

He was behind bars Friday, a day after appearing in court, pleading not guilty and being ordered held without bail.
