Yorkshire Ambulance Service received 1,570 emergency calls from New Year’s Eve into New Year’s Day.
The calls were received over the 12-hour period from 6pm on December 31, 2014 to 6am on January 1 and 897 of these (57%) were between midnight and 6am.
The busiest time was in the early hours of the morning and between midnight and 3am there were 51 emergency calls to assaults.
Paul Mudd, Locality Director of A&E Operations at Yorkshire Ambulance Service, said: “In the early hours of New Year’s Day we received a significant number of emergency calls to patients who had been assaulted while out celebrating the start of 2015. Clearly this is distressing for those directly involved, but it also places extra pressure on us and partner services.
“New Year’s Eve aside, demand for our service continues to increase.”
Police responded to almost 1,200 calls between 6pm on New Year’s Eve and 4am on New Year’s Day.
