Video: Olympic Park now in security lockdown until the Games The Olympic Park closes to the public on Thursday until it reopens to welcome athletes, VIP's, spectators and journalists from around the world. The Metropolitan Police Service is keeping a close eye on the Olympic Park and on Wednesday police divers checked the waterways which criss-cross the east London site for any security threats. The government is at pains to stress that security will be tight and officials vigilant during the Games, but that it will not detract from people's enjoyment of the spectacle. Our focus is that security should be visible yes, but not getting in the way of the Games and the enjoyment itself. We are prepared for a range of different issues, from counter-terrorism, organised crime, potential protests as well as incidents, accidents, other things that may simply occur," said James Brokenshire, minister for crime and security at the Home Office. A mix of military, police, private security and volunteer guards will be on show at Olympic venues during the Games and Paralympic Games this summer although the government says it will be no more obtrusive than at other Olympics.
