Ottawa police say an 18-year-old man apprehended Sunday in a reported assault at Carleton University has also been charged with an incident a week earlier.

On Oct. 30, a 19-year-old female student at Carleton said she was sexually assaulted as she walked towards her residence area of the university.

Carleton University staff released a description of the suspect.

On Sunday, university security was advised of an assault of another 19-year-old woman and arrested a man at the scene. He was then turned over to Ottawa police.

Police have charged the man with sexual assault and assault in connection to the two incidents.

He is scheduled to appear in an Ottawa courtroom court Monday.

Another university sexual assault on Friday

Also on Monday, the university sent an email to students regarding a sexual assault that occurred on Friday, which security believes is unrelated to the other assaults.

The statement said a female student reported being "sexually touched" by an unknown man in the university tunnel near Southam Hall around 10:30 p.m.

The suspect is described as Asian, in his early 20s, standing about five feet two inches and weighing between 140 and 150 pounds. The victim also described the man as clean shaven and with no visible distinguishing features, scars or tattoos. She told university safety he was wearing a black fall jacket and blue jeans.

The suspect may also have been seen leaving campus in a black SUV. The university's department of safety is now working on this case with Ottawa police.

University Safety is asking people with information that could help the investigation to call 613-520-4444.
