A 24 year-old Harrow man was dragged from his car and assaulted in Watford.
The man was driving an Alfa Romeo in the Alexandra Road area of Watford at 10.30pm on Sunday March 23 when he became lost and a car stopped in front of him.
Four men then got out of the silver saloon car and assaulted him before taking two phones.
The victim suffered bruising to his face and sustained a fractured pelvis.
Hertfordshire Constabulary is appealing for witnesses and information.
The driver of the saloon car is described as a man in his late 20s, with light-coloured skin and a medium build.
The second suspect is described as a white man, aged around 30 and is slightly muscular. The second suspect is also believed to have been wearing a blue hooded top and tracksuit.
