Egyptian authorities arrested 25 Muslim Brotherhood students in clashes that erupted at Ain Shams University on Monday, a security source from the interior ministry said.
Confrontations erupted between security forces and pro-Brotherhood protesters at the university earlier, escalating into chases in leading streets.
The source said in a statement published on the interior ministry's Facebook page that the Brotherhood students gathered in Khalifa al-Maamoun Street and blocked the road while security forces warned them in vain.
He added that security forces then intervened to disperse the protesters with teargas after they were attacked by birdshots which injured one conscript in the face.
The statement said that two of the suspects were carrying birdshot rifles and a teargas bomb.
Pro-Brotherhood students have organized many demonstrations at different universities since the army's ouster of Islamist President Mohamed Mursi which they consider a coup.
Mursi was deposed in July in response to mass demonstrations across the country, calling for his resignation.
