Police say ten people have died following a shooting at a ballroom dance studio in the Californian city of Monterey Park in the United States.

They say another 10 people are injured and the suspect remains at large.

The shooting happened at about 10:20 pm on Saturday.

Thousands of people had earlier gathered in the city for the Monterey Park Lunar New Year festival.

The Los Angeles County Sheriff’s Department said they are seeking a male suspect who fled the scene but did not provide any other details about him.

A police captain said that emergency services arrived on the scene and found patrons “pouring out of the location screaming”.

Officers then confirmed 10 people had died.

At least 10 others have been injured and are in local hospitals, where their conditions vary from stable to critical.

Investigators said there was no clear motive and it was too early to say whether the incident was being treated as a hate crime.

They confirmed that Sunday’s Lunar New Year festival events had been cancelled.
