The 35-year-old was with his wife Faryal in Leyton in April when he was approached by two males who threatened him with a gun before stealing his £70,000 ($85,530) watch.

Scotland Yard said three men, aged 25, 34 and 20, were arrested on suspicion of robbery after warrants were executed by detectives on Wednesday morning.

The 25-year-old has also been arrested on suspicion of possession of a firearm with intent to cause fear of violence, while the 20-year-old has been arrested for this offence and possession of ammunition.

All three remain in custody.

Officers were called to the incident on High Road at 9:15 pm (2015 GMT) on April 18.

No shots were fired and nobody was injured.

Detective Sergeant Lee Warrington of the Met’s Specialist Crime Command said: “Tackling robbery is a key priority for the Met and these arrests demonstrate our commitment to taking those intent on using violence, or the threat of violence, off of our streets.”
