LAWRENCE — A man living in the Tower Hill neighborhood who police say sexually assaulted teenage girls and provided them with cocaine was held without bail after his arraignment on numerous criminal charges Tuesday. 

Carlos Rivera, 47, of 59 Bellevue St., Lawrence, was charged in connection with the death of 13-year-old Chloe Ricard of Amesbury, who he is accused of leaving dead at the Lawrence General Hospital emergency room last Monday. Ricard was pronounced dead immediately, according to investigators.

Rivera also is accused of indecently assaulting a 16-year-old girl on an earlier date, authorities said. 

Arrested early Saturday morning, Rivera was charged with two counts of distribution of Class B drugs — cocaine — to a minor, two counts of indecent assault and battery on a child under 14, and one count of indecent assault and battery on a person over 14, authorities said. 

He was held on $750,000 cash bail through the long holiday weekend and is due back in court for a detention hearing next week.

An autopsy was scheduled on Ricard’s body last Tuesday, the day after she was pronounced dead. The cause and manner of the girl’s death has not yet been revealed. 

Ricard was a former Amesbury public school student and most recently a student at the Solstice Day School in Rowley.

Previously, Rivera was issued a speeding ticket and arrested for driving without a license. Other than that, he has no previous criminal record, according to court documents.
