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.
Det Insp Sarah Bradley said: "We fully recognise the distress and concern this incident has caused and can confirm a comprehensive investigation remains ongoing.
"We continue to work closely with our partners at the university to provide reassurance to students and staff and remain fully committed to supporting victims and safeguarding those who live, study and work in Huddersfield."
