A 29-year-old man has been arrested after seven women reported being sexually assaulted in and around the University of Huddersfield's grounds.
West Yorkshire Police said it attended the university on Tuesday evening after being called by its security office and established all of the incidents happened between 18:00 and 18:30 GMT.
A spokesperson for the force said the women "had made off from a suspect after he approached and grabbed at them", with the arrested man remaining in police custody.
Prof Tim Thornton, the university's deputy vice-chancellor, said they recognised the incidents were "deeply concerning" and had "increased security patrols around campus".
He added the university was encouraging "all members of our community to make use of our SafeZone app, which provides direct access to emergency assistance, wellbeing support and our campus support and safety team."
Thornton said the university was working closely with police and that "the safety and wellbeing of our students, staff and visitors is our highest priority".
He added: "We remain committed to maintaining a safe and supportive environment for everyone who studies, works and visits our campus."
Det Insp Sarah Bradley said: "We fully recognise the distress and concern this incident has caused and can confirm a comprehensive investigation remains ongoing.
