Nicola Sturgeon raises Hampden Park Olympic football security concerns

Scotland's deputy first minister has written to the UK home secretary seeking reassurance on security arrangements for the Olympic Games.

Nicola Sturgeon has asked Theresa May about the eight Olympic football matches being played at Scotland's national stadium.

The first game is due to be played on 25 July.

Ms May has previously said there is "no question" of Olympic security being affected by problems at contractor G4S.

Strathclyde Police said on Thursday extra police officers would be deployed at Hampden if there were not enough stewards and security guards.

But Ms Sturgeon said she was concerned about reports that training for security staff was behind schedule.

She said: "It is particularly worrying to learn of suggestions that, in some instances, training may not be delivered to G4S staff until after the football has actually taken place in Glasgow.

"The Cabinet Secretary for Justice (Kenny MacAskill) and his officials have been keeping in close contact with Strathclyde Police and Mr MacAskill is confident in their ability to police the Games.

"Nevertheless we would be grateful for a firm and immediate assurances that any individual being employed at Hampden will be suitably qualified and trained."
