Olympic security: police offers from regional forces drafted in to make up for G4S shortfall The officers have been called up to help 'lockdown' the six football venues and hotels that will be used by teams in Cardiff, Glasgow, Coventry, Manchester and Newcastle. "We have identified that there is a shortfall, and the extra 3,500 troops and police officers are assisting in providing the additional security we require," he said. Police from around the country are being used. Our 'football force' is slowly going out and helping with lockdown at hotels, and we are working hard with them to assist where there is a shortfall. G4S, whose share price fell sharply in London on Monday morning, has trained and deployed just 4,000 of the 10,400 staff it was contracted to provide.
