Police are appealing for help tracking a man wanted in connection with a shooting at a 10-year-old girl's birthday party.

Police are asking for information on Alfie Gannon, 20, who is alleged to have shot a 22-year-old man in front of his stepson in Bromley, south-east London.

No children were harmed in the shooting, but police said they were left "extremely traumatised" by the incident.

Metropolitan Police said Gannon was asked to leave the children's party after getting into an argument with one of the family members.

Whilst leaving the property, Gannon is alleged to have threatened to kill the man he was having an argument with.

Police say he returned to the party a short time later and asked for the brother of the man he was arguing with to come outside.

Gannon is the alleged to have shot the man in the leg with a semi-automatic pistol in front of his seven-year-old stepson. The victim made a full recovery from his injuries.

Police are now asking help to track down the suspect, who has links to the West Yorkshire area, but have warned the public not to approach him.

Detectives from the Met's Trident Gang Command Unit are investigating the shooting.

Det const Paul Buckley, said: "This was a shocking incident at a child's birthday party. Understandably both the children and guests at the party where extremely traumatised by the senseless actions of the suspect.

"I would like to reassure any potential witnesses who may be worried about making contact with police that Trident has extensive expertise in protecting witnesses and there are a range of measures that can be taken to protect you.
