Police are searching for a teen in connection with three robberies and sexual assaults of Temple University students since the beginning of February.

The first attack, police said, happened on Feb. 3, shortly after 11 p.m. on Fontain Street near 17th.

"The female was approached by the teen who asked if he could use her cell phone," said Special Victims Unit Lt. Mike Boyle.

Boyle said the 21-year-old victim was then pushed to the ground and the punk unzipped his pants and pushed his exposed groin up against the woman's head.

He also tried to snatch her purse but could only make off with her cell phone, Boyle added.

The second incident happened on Feb. 7, shortly before 8 p.m. on Diamond Street near 18th, according to police.

"A 21-year-old student was grabbed from behind and he placed what appeared to be a knife to her neck and asked for money," Boyle said.

The assailant then felt the woman's pockets, unzipped her pants and groped her, police said.

He fled down Diamond Street with the woman's purse which contained $200 and a cell phone.

The third attack happened Monday on Carlisle Street near Diamond shortly before 5 p.m. when a 19-year-old student was approached by a teen who again asked to borrow her cell phone, police said.

She refused and he grabbed her phone and repeatedly asked her for a hug. He pulled her toward him several times, embracing her, prior to running off with her phone.

Yesterday, Theresa Powell, Temple's vice president for student affairs, warned students about the incidents and provided them with safety tips.

Boyle said, "Be aware of your surroundings, don't shut yourself off with iPods or cell phones. Travel in pairs if possible." *
