Detectives are appealing for information following a robbery in a busy Brent street.
Police were called to Abbey Road, NW10, at 12:23hrs on Wednesday, 21 December to reports of a robbery.
The victim - a man in his 50s - was about to enter the Natwest bank at around 12:15hrs when he was approached by the suspect.
A struggle ensued and the suspect grabbed the banking bag the victim was carrying before fleeing the scene.
The victim followed the suspect and he believes that he saw the suspect hand over the bag to a man in a blue van. The van driver was confronted but he drove off down Abbey Road. The victim then called the police.
The suspect who snatched the bag is described as a white man, about 5ft 9ins tall and had an eastern European accent. He was wearing an orange t-shirt.
The victim was unable to give a detailed description of the van driver other than he was a black man.
PC Natasha Bennett, the investigating officer from Brent CID, said: "This incident has left the victim very distressed and we are determined to catch those responsible and put them before the courts.
"Abbey Road is a busy area and there would have been a number of people around on the afternoon of 21 December. We would urge anyone with any information, or any witnesses to contact police."
