LONDON - British police on Monday launched an anti-terrorism campaign and called on the public to help find potential terrorists.

The British police, government and armed forces have increased their vigilance for terror attacks since the beginning of 2012, as part of a strategy to protect the London Olympic and Paralympic Games from terrorist attacks.

London's police force, the Metropolitan Police, is the driving force behind the latest campaign, and the coordinating body for Britain's anti-terrorism strategies as well as the police force responsible for most of the Olympic and Paralympic Games venues.

"The terrorist threat to London, and Britain generally, remains real and serious, so it is vital that everyone continues to be vigilant and aware," said Metropolitan Police Deputy Assistant Commissioner Stuart Osborne, who is also senior national co-ordinator for counter terrorism.

"We at the Metropolitan Police Service have a key role in countering this threat, whether it is from Al-Qaida inspired groups or individuals, or Irish Dissident Republican Groups."

Osborne called on ordinary members of the public to report anything suspicious, no matter how trivial it might seem, and also called on family members to contact police if they believed something suspicious was going on.

The campaign will run over the next four weeks, with a high profile in local newspapers across London, on the radio, and via leaflets distributed to 1.4 million homes.

The appeal came with just 165 days to go before the London Olympic Games starts on July 27.
