Police are looking for a man who has groped at least three Loyola University students and one faculty member on or near the school’s Rogers Park campus in recent weeks.

A student was walking in the 6500 block of North Kenmore about 10 p.m. on Sept. 6 when she felt someone touch her buttocks, according to a community alert from Area North detectives. When she turned around, the suspect was riding away on a bicycle.

Another student who had left the campus library was walking home in the 6300 block of North Winthrop about 12:30 a.m. on Sept. 7 when a man rode up behind her on a bicycle and touched her buttocks, police said. He rode past her a second time and touched her breast before riding off north on Winthrop.

A faculty member was walking to campus about 9:05 a.m., also on Sept. 7, in the 1600 block of West Greenleaf when a man on a bicycle grabbed her buttocks before riding off, police said.

A student was in the 6300 block of North Winthrop about 10:30 p.m. on Sept. 18 when she walked past two males leaning on the fence in front of a campus building, police said. One of the two males walked up and touched her buttocks before walking away.

The suspect was described as either a Hispanic or Middle Eastern man in his early 20s, police said. He has dark skin and dark, wavy hair. He was riding a mountain bike during the attacks.

Chicago Police said the Sept. 6 and Sept. 18 assaults were handled only by the Loyola campus police and were not reported to the CPD. Loyola issued campus alerts after the second and fourth attacks were reported.

Anyone with information on the man is asked to call Area North detectives at (312) 744-8200.
