Ottawa police have made an arrest related to two assaults of Carleton University students, as campus was informed of a third, unrelated sexual assault on Friday.

Police said 18-year-old Oluwatimilehin Akindele was arrested by Carleton University security on Monday after a 19-year-old female was assaulted off-campus on Sunday.

He was then turned over to Ottawa police.

Akindele has been charged with assault in connection with that incident and sexual assault on Oct. 30 where another 19-year-old female student was groped on campus.

Ottawa police were not called after the first assault, which campus security said happened as the survivor walked between Stormont and Dundas residences around 3:30 a.m.

Separate assault reported on Friday

Students then received an e-mail from campus security just after 2:00 p.m. Monday about an unrelated sexual assault on Friday night.

The e-mail said a female student was sexually touched at 10:30 p.m. Friday as she walked in the campus tunnels near Southam Hall.

The suspect is described as an Asian male in his early 20s, standing five foot two inches tall and weighing between 140 and 150 pounds.

Security said he is clean-shaven with a clear complexion and has no distinguishing scars or tattoos. He was wearing a black fall jacket and blue jeans and may have been seen leaving campus in a black SUV.

The school said its campus is still safe.

"Two incidents like this in a short period of time is not a normal thing at Carleton University," said director of university safety Allan Burns. "Carleton continues to be one of the safest campuses in Canada to live, to study on as well for as our faculty to work on."

The student residence group said they're now offering self-defence classes after the recent assaults.

"Now that it's happened, especially twice in one week, it's evident that there's a growing issue and the students need to be aware of what's happening and a whole lot more cautious," said Kaisha Thompson with the Rideau River Residence Assiciation.

Carleton University said they increased security after a 2007 attack on a female student in a computer lab, but some students are still fighting for a dedicated sexual assault centre on campus.

The Coalition for a Carleton Sexual Assault Centre said the school ignored a student referendum that gave 80 per cent support for their student-run, university-funded centre.

They said they want the school to stop blaming victims of sexual assault, as they said they did when they responded to a lawsuit filed by the survivor of 2007's attack when the school said she shouldn't have been alone on campus at night.

They said they want the school's response to be more proactive rather than reactive when dealing with incidents of sexual assault.
