United Airlines said 10 people suffered injuries after a Los Angeles-to-Chicago flight was caught in the middle of turbulence in Nevada.

The Chicago-based airlines said Flight 1028 was diverted to Denver International Airport around 3 a.m. Monday after encountering heavy turbulence, the Associated Press reported.

Eight passengers on board and two flight attendants suffered injuries during the incident and were taken to several hospitals in Denver, a spokesperson of the airline said. The doctors dealing with their cases have not released their condition yet.

“We don’t have their conditions at this time,” said United Airlines representative Megan McCarthy, according to local newspaper Denver Post. She also said that a further and complete investigation would be led on the case. “We don’t have details about exactly what happened,” she added.

Flight 1028, which was coming from Los Angeles and heading to Chicago O’Hare, was carrying 187 passengers.

United Airlines’ maintenance employees reviewed the Boeing 757 and “everything checked out OK,” McCarthy said.

After getting a new crew, the plane continued onto Chicago at 5:44 Tuesday morning, arriving at Chicago O’Hare Airport at 9:40 a.m.

A voicemail left at United Airlines’ main number, seeking for further details on the incident, was not immediately returned, Bloomberg reported.
