A party of travellers trashed a country golf club after the free bar ran out
More than 200 people turned up for a party at the Stapleford Abbots Golf Club in Romford, Essex, which had been booked for just 50 people.

When staff tried to intervene, the travellers wreaked havoc on the venue, knocking over chairs and hurling rubbish across the floor.
Police described the incident on Tuesday night as a "large scale public order incident" and tweeted pictures of the chaos.
