A POLICE HELICOPTER has crashed into a pub in Glasgow causing multiple injuries, police and witnesses said.

Police Scotland have confirmed that Eurocopter EC135 T2 with a crew of three consisting of two police officers and a civilian pilot were on board the helicopter.

Firefighters, paramedics and police are at the Clutha pub in Stockwell Street but there is “no immediate confirmation of casualties”.

They added: “At present Police Scotland is not in a position to confirm any details regarding injuries.”

The Scottish police stated that the incident happened at 10.25pm and emergency services responded immediately and remain at the scene. The police said cordons are in place to allow the rescue operation to take place.

Alex Salmond the First Minister of Scotland tweeted: “Rescue efforts in full operation. Given an incident of this scale we must all prepare ourselves for the likelihood of fatalities.”

Gordon Smart, editor of the the Scottish edition of Rupert Murdoch’s Sun newspaper said:

“It was just such a surreal moment. It looked like it was dropping from a great height at a great speed. I’m about 80 percent sure that it was a police helicopter,” he told Sky News.

“There was no fireball and I did not hear an explosion. It fell like a stone. The engine seemed to be spluttering.”

A woman who was in the bar at the time, Grace McKeen, told Sky News they didn’t hear any noise, but they did hear a “whoosh” sound. She said it looked like the roof was “gradually” and slowly caving in and the band, who were playing in the pub, stopped playing their music.

She said that there was no explosion, but just a “cloud of dust”. She said they didn’t know that a helicopter had hit the roof until someone had told them.

McKeen said she didn’t see anyone with any serious injuries and people seemed to be conscious.

It’s believed there were a lot of people in the bar due to the band playing there this evening.

The Facebook page of the band, that are believed to have been playing in the bar have updated their Facebook page stating that the band members are “OK”. Just below the post, is the band’s post advertising their gig in the Clutha pub.

Jim Murphy, a Labour party member of parliament and spokesman for defence, told the BBC he was driving through the area “just a few seconds after what seems like a helicopter has crashed into a pub”.

Murphy said he had seen “multiple injuries”.

“It’s a well established Glasgow pub. It’s a horrible horrible scene, but well done to the folk who were here. Everyone formed a chain of people from inside the pub to outside, and the fire brigade and everyone were here very quickly.”

Scotland’s Deputy First Minister Nicola Sturgeon said it was “awful news”.

The Scottish Fire and Rescue Service said they were on their way to a “building explosion” in Glasgow’s Clyde Street.

However, Sky News is reporting that no fire has broken out at the scene of the crash and at least 15 fire fighters are at the scene.
