London Ambulance Service has put out a plea after fireworks were aimed at one of their vehicles last night.

In a tweet they said: "We can’t believe we have to say this, but aiming fireworks at our ambulances is #NotPartOfTheJob

"The crew - who were driving on blue lights to an emergency - were forced to swerve & stop."

Luckily there weren't any patients in the back, but that isn't the point.

Whoever thought this was a funny idea put the crew in danger and this isn't and will never be acceptable.

LAS later tweeted: "Thank you for all the support on this post, which the crew have seen too.

"Sadly this isn’t the first time it has happened.

"Putting crews in danger in such a way & potentially harming patients or delaying/stopping us from helping someone in need is unacceptable & #NotPartOfTheJob."
