Met officers arrested four people last Friday, 30 August relating to a robbery at a post office on Brabazon Road, Hounslow in April of this year.

During the incident, a man is alleged to have entered the post office and threatened the shopkeeper with a firearm while demanding cash.

The Met say he is believed to have forced one of the staff members to access the safe room where he is suspected of stealing £136,774.44.

Witnesses alleged that the suspect ordered both employees into a back room where he removed the CCTV hard drive, before escaping.

As part of the investigation, officers discovered that the alleged robbery was potentially part of a wider conspiracy involving additional people.

Detectives pursued lines of enquiry and specialist officers executed search warrants at several locations in London, Surrey and Hampshire.

Four people, including two men aged 38 and 65 and two women aged 39 and 44 were arrested for:

• Conspiracy to steal
• Conspiracy to possess criminal property
• Conspiracy to pervert the course of justice

The Met Police confirm that the 65-year-old man was released on bail while the other three people were charged with the above offences and remanded in custody by Wimbledon Magistrates.

They will next appear at Isleworth Crown Court on Friday, 27 September.

Previously, a man has been charged in relation to this matter the Met say.

Detective Inspector Ari Yoganathan, who is leading the investigation, said: "We know our communities stand firm with us against the use of firearms and support us in our efforts to tackle robbery.

"We are committed to reducing crime that impacts our communities and keeping residents, businesses and staff safe."
