There was an emergency incident on the tram tracks at Carbrook, Sheffield, last night but details of what exactly happened have not yet been released by South Yorkshire Police

Although despite being contacted for details on the nature of the incident and whether anyone lost their life, South Yorkshire Police has not yet responded or issued a statement.

The force has been contacted again this morning.

South Yorkshire and Rescue Service said last night: “We are in attendance at an on-going, multi-agency incident on the Stagecoach Supertram line in Carbrook, Sheffield.

“Please expect delays and avoid the area whilst we work.”

Reports on social media suggested that there had been a collision.

Other messages on social media described passengers stuck on trams between the arena and Meadowhall for several hours.

One eyewitness said on Twitter: “We’re at the Premier Inn next to the tram line and there are five fire engines and multiple ambulance and police. No idea what’s going on but hope everyone is ok.”
