Police are continuing their search for a man who jumped into River Haven in Boston on Monday night.
Emergency services were called to the area of High Street at about 9.45pm on December 23, after reports that a man believed to be in his thirties fell into the River Haven.
They searched with a Lincolnshire Fire and Rescue boat and along the river bank, as well as using the police drone and the regional police helicopter, both fitted with heat seeking equipment.
The search of the river was called off at 1am on December 24 until daylight, but ground searches along the river continued through the night.
The man is believed to be 33-years-old and he reportedly jumped into the river, which had a very strong current last night.
Police are continuing to search on Tuesday using drones and the fire service is continuing to support.
Chief Inspector James Trafford says: “The emergency services and Coastguard agency carried out extensive searches last night to locate this man and these efforts have started again today.
“We do not yet know why this man has decided to jump into the river, but we are working to understand why this happened.
“If anyone has information which may help us, please get in touch.”
