More than 300 Northamptonshire police on New Year's Eve duty
A team of more than 300 officers and 50 police community support officers (PCSOs) will man Northamptonshire's streets during new year celebrations.
Nightclubs, bars and queues for hot spots will be among areas checked by officers overnight.
The "robust and dedicated'" team will be equipped with body cameras to record the evening, the force said.
Chief Superintendent Richard James who is leading the operation said it planned a "highly visible presence".
Plans are in place to deal with a range of revellers including ones who are violent, injured or vulnerable, police said.
Those who sustain minor injuries during the evening will be able to receive treatment from mobile units attended by officers and staff from the East Midlands Ambulance Service and St John Ambulance.
The Street Pastors, a community initiative which offers help, support and advice to vulnerable people in the county's town centres will also be in operation.
A police spokesperson said: "We are confident that we have a very robust and dedicated response team working over the New Year period."
