An MS-13 gang member is behind bars after, police said, he sexually assaulted his girlfriend’s 2-year-old daughter in a rampage in Hempstead that included stabbing the child’s mother and another woman who suffered a collapsed lung.

Tommy Vladim Alvarado-Ventura, 31, pleaded not guilty Thursday to charges including predatory sexual assault on a child at an arraignment that followed his arrest Wednesday at his Hempstead apartment, where police said that crime took place.

Acting Nassau Police Commissioner Thomas Krumpter called the case “nauseating,” saying it was “probably the most heinous criminal act” he’d come across in 28 years of police work.

The Hempstead man also faces an attempted murder charge and multiple counts of assault and weapon possession in an alleged crime spree authorities said followed the man’s repeated return to the United States after four deportations to El Salvador.

Authorities deported Alvarado-Ventura in September 2006, September 2009, April 2010 and in December 2011, when Nassau probation officials turned him over to Homeland Security officials after he did jail time, Krumpter said.

Hempstead District Court Judge Joseph Girardi remanded Alvarado-Ventura to Nassau’s jail without bail after prosecutor Amanda Burke called the case “particularly horrific.” She said the toddler needed surgery because of the sexual attack, and also suffered a severe beating to her head and face.

Police said the violence unfolded between late Tuesday and early Wednesday, including when Alvarado-Ventura was in the Fulton Avenue apartment he shares with his girlfriend.

He arrived there about 11:30 p.m. Tuesday. A male tenant was baby-sitting the toddler and her 4-year-old brother, according to authorities. They said the toddler was crying when Alvarado-Ventura left at 12:30 a.m. and went to nearby El Mariachi Loco bar.

About 2:20 a.m., Alvarado-Ventura argued with a 24-year-old woman inside about buying marijuana before he punched, kicked and repeatedly stabbed her in the parking lot after she left the bar, according to police. Besides a collapsed lung, the victim had stab wounds to her back, thighs and mouth, Burke said.

He went home about 3:15 a.m. When his girlfriend returned from work and saw the severe injuries inflicted on her daughter by Alvarado-Ventura, she confronted him, police said. Alvarado-Ventura then attacked his girlfriend, repeatedly punching her in the face and stabbing her in the back, neck and one of her hands, according to authorities.

Police said the woman was able to get her children into another area of the apartment, and after Alvarado-Ventura fell asleep, got a neighbor to call for help before police arrived and arrested him.

The judge signed orders compelling Alvarado-Ventura not to contact the victims, all of whom police said were hospitalized.

Police said the timing of the attack on the toddler was still under investigation, as were the circumstances of Alvarado-Ventura’s deportations — at least one of which resulted from a criminal conviction. They said they have no indication the crimes of which he is now accused were gang-related.

Police said he had multiple prior arrests in Nassau. Records show Alvarado-Ventura got a 45-day jail term after pleading guilty to DWI after a February 2008 arrest, and 15 days in jail after pleading guilty to resisting arrest and false impersonation after an October 2008 arrest.

After a 2009 arrest, he got a six-month sentence for an aggravated criminal contempt charge, records show. And records also show he received a 1-year sentence after a guilty plea to a criminal contempt charge after a 2011 arrest.
