Police in London dealt with more than 4.5million calls last year, it has been revealed. 

A total of 4,576,521 calls were answered by operators at MetCC, the UK's largest police command and control unit.

Of that total, 1,767,414 were 999 emergency calls and 2,809,107 were via the 101 number.

A total of 482,255 were designated as grade one, requiring an immediate emergency response.

The Met's target is to respond to those calls within 15 minutes 90 per cent of the time.

This was achieved, with the target hit 92.6 per cent of the time.

Each emergency call was answered in an average time of five seconds, while 101 call were answered in an average of ten seconds.

The busiest day of the year was October 31, with 8,657 emergency and 9,760 non-emergency calls. 

The busiest month of the year was July, with 164,308 emergency calls and 260,503 non-emergency calls, which police claim is because of the warmer weather and more people on the streets.

Christmas Day last year saw 3,199 emergency and 2,669 non-emergency calls, Boxing Day saw 3,870 emergency and 3,831 non-emergency calls and there were 6,499 emergency and 6,414 non-emergency calls on New Year's Eve.

Chief Superintendent Pippa Mills, head of MetCC, said: "It has been another very busy year for our call operators, not least Halloween which saw us answer an average of 767 calls coming in across London every hour.

"These figures demonstrate how incredibly hard our call operators work and I am proud of the professionalism they show, particularly when dealing with distressed members of the public who urgently need our help."
