A man in his 20s suffered serious facial injuries following an assault at Huttoft Bank.
The incident is said to have happened at around 4am in the early hours of Sunday morning during a ‘gathering’ of a number of people on the beach.
It was around the same time people in the area reported a possible ‘rave’ though it’s not clear if the incident is connected.
A local man, 28, has been arrested by Lincolnshire Police and has been released under investigation.
Lincolnshire Police are now appealing for any witnesses to contact them on the non-emergency number 101 quoting incident 337 of July 1. Witnesses can also email the force putting the incident reference in the subject line.
