Four stabbed as violence erupts in three London areas

Four people have been stabbed and a number of others injured after violence broke out in three London areas as soaring temperatures gripped the capital.

Three people, including a police officer, were stabbed when a water fight at Hyde Park in the heart of the capital turned nasty, and four officers and a member of public also suffered injuries.

And in Burgess Park in south London there was another stabbing as disorder broke out among 300 people gathered there for an end-of-term water fight in the sun.

There was further violence well into the night when police were pelted with missiles as they moved hundreds of people from an illegal rave in north London.
