Detectives have launched an investigation after a bullet hole was discovered in the front door of someone's home.

Police were called at around 10.30pm on Sunday (October 11) to the Grahame Park Estate in Colindale to reports of a bullet being fired.

The Metropolitan Police say no one was injured and believe at this stage, the attack may be have been a case of mistaken identity.

No arrests have been made but CCTV enquiries are ongoing and investigating officers are appealing for witnesses and information.

Detective Constable Michael Clinch said: "This has left those who were inside shaken and distressed but, thankfully, not injured. They have no idea why anyone would target their home and we are in close contact with them as we investigate what happened.

"Rest assured we are conducting extensive enquiries to find out who was responsible for this reckless attack.

"I need to hear from anyone who has information about this incident. Communities have a vital role to play in tackling violent crime and we urge anyone who may have information to tell us, so that we can tackle violence together.

"Community intelligence can be used to great effect to not only detect, but also prevent crime, keep London safe and save young lives."
