LONDON— Six people, including three children, were injured Sunday after a car ran into a large crowd gathered to celebrate the Muslim holiday of Eid al-Fitr in the northern English city of Newcastle. Police said there was no information suggesting the incident was terror-related. Police believe a woman who had been celebrating Eid with her family was driving the car that struck the crowd outside the Westgate Sports Center, Assistant Chief Constable Darren Best said. Northumbria Police arrested the woman, 42, who remained in custody. The force said it was not looking for other suspects. "We have no information to suggest this is terror-related, however, this is a serious collision with multiple casualties and extensive inquiries are ongoing to establish the circumstances around this tragic incident," Best said. The collision took place outside the sports centre when many were just leaving a prayer gathering marking the end of Ramadan, according to the nearby Newcastle Central Mosque, which organized the Sunday morning family event called "Eid in the Open." "Immediately after the Eid prayers when the people were starting to leave the venue, a car collided with pedestrians. The injured were immediately attended to by the emergency medical services and the police," it said.
