Police were alerted to the presence of a suspicious commuter by a ticket collector. When police officers attempted to establish his identity, the man attacked them, trying to bite the law enforcers, according to a police account of the incident.
The 23-year-old continued to attack the officers and tried to grab a police pistol even after he was put in handcuffs with the help of a third police officer. All that time, he shouted "Allahu Akhbar" and "Daesh".
Eventually, officers used pepper spray to subdue the attacker. One officer received a knee injury and another was bitten in the forearm and had a rib cracked. The third officer sprained his hand.
