BRIDGEPORT — A local man awaiting trial for allegedly sexually assaulting an 11-year-old girl in 2015 has been charged with sexually assaulting a 14-year-old girl in 2017.

Brian McAllister, 42, was served Friday with the new arrest warrant in prison, where he is being held in lieu of bond on the earlier case.

He is charged in the warrant with second-degree sexual assault and risk of injury to a minor.

Superior Court Judge Tracy Lee Dayton ordered McAllister held in lieu of an additional $150,000 bond and continued the case to Oct. 7.

McAllister’s public defender, Jared Millbrandt, declined comment on the arrest.

The alleged assault on the 11-year-old girl was one of several cases the Bridgeport detective bureau worked on after the Youth Bureau was disbanded in 2018, in part because cases assigned to the Youth Bureau were often not followed up. Over the past year, several of the cases started by the Youth Bureau and moved to the detective bureau have resulted in charges against alleged perpetrators.

On Jan. 20 of this year, McAllister was charged with first-degree sexual assault of a child, risk of injury to a child and fourth-degree sexual assault based on a complaint by the 11-year-old girl in 2015.

Police said in the newest case, McAllister is accused of sexually assaulting a then-14-year-old in an office at Housatonic Community College.

According to the new arrest warrant affidavit, in March 2019, the victim reported to the state Department of Children and Families that in 2017 she was visiting Housatonic Community College with a friend when she met McAllister, who invited her to wait for her friend in his office at the colleges’ Men’s Center.

According to the affidavit, college officials told police McAllister was a work-study student there.

“We are deeply distressed to learn that a former student, who attended HCC from 2016 to 2018, is accused of committing a serious crime while on the campus,” college spokeswoman Evelyn Gard said Thursday. “The incident, which we are told occurred in 2017, was not reported to anyone on campus, therefore college officials were unaware of any misconduct. The matter has been, and remains, in the hands of the Bridgeport Police.”

Police said, during a forensic interview, the girl told them McAllister warned her to stay away from boys then sexually assaulted her, the affidavit said.

The assaults continued into 2018, the affidavit said, with the girl estimating she was sexually assaulted in the college office and McAllister’s car more than 10 times.

The affidavit said that McAllister and the victim’s DNA was found on the office couch.
