This is why fire crews were at a Doncaster prision earlier this week

Several appliances from Askern, Rossington, Thorne and Doncaster fire stations all were all at HMP Lindholme, surprising locals.

But instead of a full scale live incident, the engines were there for a training exercise.

A spokesman for Askern Fire Station said: “Working together with on site staff to assess our interoperability and operational plans.

“The exercise was a huge success.”
