Two Chestnut Hill men were detained and charged for sexually assault against two female students in a Boston University dormitory, according to authorities.

Apparently the two men, neither one a Boston University student, convinced two residents of the BU dormitory to sign them in early Sunday, as they didn’t have their IDs on them, BostonHerald.com reports.

According to BU officials, this is against university policy.

After that, Daniel Glaser, 20, and Aaron Goodliss, 21, went to the 12^th floor and tried every door to see which was unlocked.

Glaser entered in a room while Goodliss waited outside in the hall. Glaser allegedly groped an 18-year-old student who was sleeping until she awoke and threw him out.

In the second room, Goodliss stood in the hall while Glaser tried to climb his way up to a raised bed and groped the woman.

They’ve left the floor, but they were caught by police campus around 4 a.m.

Glaser, who is attending Lehigh University in Pennsylvania, was charged with one count of breaking and entering at night with the intention to commit a felony, two counts of indecent assault and battery and two counts of unarmed burglary.

Goodliss, a student at Johnson & Wales University in Providence, received charges for breaking and entering at night and also for possession of a substance.

According to Boston University police officers, they’ve found a small amount of marijuana on Goodliss.

They were initially set cash bail of $25,000 by the Assistant District Attorney Megan O’Rourke, but afterwards Brighton District Court Judge David T. Donnelly set a lower bail, $7,500 for Glaser and $2,500 for Goodliss.

They were released on bail after they both pleaded not guilty to the charges.

They are to return next month to Brighton District Court.

Colin Riley, a Boston University spokesman, said that the attacks a “reminder that students need to take responsibility for their guests.”
