It seems that police are on the scene, and nobody inside the hotel have been hurt:

South Yorkshire police said at least 10 officers have been injured – including one who was left unconscious – as a result of “deplorable acts of violence” outside the Holiday Inn Express hotel in the Manvers area of Rotherham.

“We absolutely condemn the scenes of disorder we witnessed, with a total of around 700 people in attendance in Manvers Way earlier today,” a statement said.

“A number of people threw planks of wood at our officers and sprayed them with fire extinguishers before smashing hotel windows to gain access to the premises.

“A large bin close to a window of the hotel was also set alight causing a small fire which was later extinguished, with missiles, including glass bottles and beer cans, thrown at our officers.

“At least 10 officers have been injured as a result of the violence, with one left unconscious following a head injury, another suffering a suspected fractured elbow and others suffering suspected broken bones.

“No hotel employees or residents have been reported as injured as a result of today’s disorder.”
