The driver of the train which was the scene of a brutal police slaying on friday morning was himself chased by armed terror police who held a gun to his head as he tried to get away from terrifying 'shoot to kill' attack.

The driver started running as passengers fled from Stockwell Tube station following the shooting of a man it has since been revealed was unarmed.

According to officials from the train drivers' union Aslef, the train driver was chased by police who on catching up pointed a gun at his head.

Hearing about this outrageous behavior by armed cops given orders to shoot to kill, many train drivers have been understandably reluctant to continue working normally, the union's London officer Steve Grant has reported.

He said this incident highlights the tense atmosphere that his members are having to cope with since the 7th July attacks.

Apparently police have since apologised, which I am sure will have made the driver involved feel much better.

So, with armed tigger happy homicidal cops running around London we now have something else to worry us. We are therefore forced to raise the unofficial terror alert to 'dont run!'.

This highten security level means - don't wear bulky or baggy items of clothing if you are dark skinned - if you see police, walk at a resonable pace away from danger - whatever you do, do not run!
