A fight between security staff and a gang of men attempting to get into a Birmingham city centre nightclub - where a man was killed last month - resulted in a dog being shot.
Police were called to the Air nightclub - home of the popular God's Kitchen events - in Digbeth at 1.35am on Monday after receiving reports of gunshots.
A group of about 15 hooded men had tried to force their way into the club in Heath Mill Lane where a post-Birmingham Carnival party was being held. During the skirmish with security staff, the dog, thought to be bull mastiff terrier, was shot.
One of the offenders may have received a bite from the dog during the incident.
Police are continuing with their inquiries and have carried out a forensic examination of the scene. On July 23, 32-year-old Jamaican national Andrew Huntley, from Smethwick, died of gunshot wounds to the head outside the same club. A man and a boy, aged 18 and 14, have appeared in court in connection with the murder.
Detective Chief Inspector Jan Thomas-West, crime manager at Steelhouse Lane, said: "We are not ruling anything out completely but we are satisfied at the moment there is no link between these incidents. It is worrying when weapons are used but if you consider the thousands of people who go out and enjoy themselves in the city centre, these incidents are extremely isolated."
She added the police were working closely with the club and would review security arrangements at the venue.
The group of men ran off following the incident and police are appealing for anyone with information, or if they know of anyone who recently suffered a dog bite, to contact CID at Steelhouse Lane police station on 0845 113 5000.
