PHILADELPHIA (CBS) — Temple University police are stepping up patrols after reports of multiple assaults involving a man on a scooter inappropriately touching women. Temple University Police issued a warning Tuesday night about the incidents and the man involved.

Temple police are actively investigating the incidents and are coordinating with the Philadelphia Special Victims Unit to get to the bottom of these assaults.

Investigators say the suspect’s MO is to ride past his victims, then touch their private body parts over their clothing.

“I think it’s gross,” Temple student Luke Cordrey said.

The assaults happened on Sept. 21st and Sept. 22nd and the most recent was this past Monday, Oct. 18. All of them occurred along Polett Walk between 15th and 16th Streets in the evening.

Olivia Rakairo is now anxious about using that route.

“My apartment was on the way, so I always go that way and sometimes later at night,” Rakairo said. “So, when I saw that, it definitely made me more nervous.”

Detectives from Temple have pulled surveillance video. That has not yet been released to Eyewitness News.

The suspect is being described by police as a Black man between 20 to 30 years old, wearing dark clothing and a mask. Officials believe the suspect’s electric scooter, coupled with over-the-calf boots that he wore in each of the attacks, will help officers and the public identify him.

“It’s a shame. It’s sad and scary,” Temple student Steve Callahan said.

“It’s very unsettling definitely, but it is definitely something when I came to Temple, I knew it was something I had to look out for,” Abby Ruane, another Temple student, said.

As the investigation continues, police are urging people in the area to be aware of their surroundings, travel with friends, walk on a well-lit, regularly traveled street or pathway and watch your back. Make sure you’re not being followed, and if you are, cross the street. If someone starts pursuing you, do whatever it takes to draw attention to yourself.

“I just make sure my friends are OK,” Cordrey said. “I wouldn’t let any of my girl friends walk home alone anyway beforehand, and definitely won’t do that now.”

Police also urged students to use the university escort service.

The police sent the following letter to students:
