More than 100 people have been moved on from a beach after police were called to reports of men and women fighting.
Devon and Cornwall Police said multiple units were called to the esplanade on Exmouth beach at about 18:35 BST on Friday, to disperse people who had been drinking alcohol.
One person had a baseball bat seized.
Officers said an investigation had begun into one report of an assault, as well as possible coronavirus lockdown breaches. No arrests have been made.
Initially police said they were called to reports of about 30 men and women fighting, but later reports suggested it was up to five.
The people involved were described as "youths" or "in their early 20s", the force added.
Officers said it was the second night in a row they had responded to reports of large numbers of people gathering on the beach.
On Friday, they found "people were generally in groups of no more than six and any crowds were dispersed".
The force said: "Some people had been drinking too much and we are investigating one report of assault in which an 18-year-old man sustained some low-level injuries described as reddening to his skin."
