Police were forced to smash the window of a car with a dog trapped inside on what is forecast to be the hottest day of the year so far.
Infuriated officers warned others not to take their dogs outside after rescuing the pet in 31.5C heat in north west London this morning.
Barnet MPS tweeted: "Unbelievably, our officers have just had to smash the window of a vehicle to get a dog out at the RAF museum Hendon. 31.5 degrees! JUST DON'T TAKE DOGS OUT IN THIS HEAT."
