Detectives investigating an alleged assault on Portland are renewing their appeal for anyone with information to come forward as they are looking for a possible injured person.
At 4.40am on Saturday July 22, Dorset Police received a report that several people entered an address on Fortuneswell which contained a number of men and threatened some of them with a knife.
A fight ensued during which it appears someone was injured.
The people then left the address, however it is unclear at this time if anything was taken from the property.
Officers, including armed officers and a dog unit, attended and searched the area.
A 43-year-old man, a 36-year-old man and a 29-year-old woman, all from the Weymouth area, and a 17-year-old boy of no fixed abode, were arrested on suspicion of assault and have been released under investigation.
