Five days later a 36-year-old woman was pushed to the ground by two men who ambushed her from behind in as she entered a block of flats in Prince Albert Road, St John’s Wood, at 7pm.

The pair stole her watch and a ring.

The last attack on February 2 saw a 44-year-old woman robbed by a man who approached her from behind in Acacia Road, St John’s Wood.

He stole her rings before fleeing on a moped at 12.20pm.

There have been no arrests so far.

Detective Superintendent Jess Ruddell, investigating officer, said: “These offences have naturally caused a great deal of distress for the victims, especially as jewellery of a sentimental value was taken. We are following up every investigative lead to catch the people responsible.

“I would stress that at this stage there are no firm investigative links between these incidents, but that in no way undermines our determination to solve them.

“I would like to ask for the public’s help - if you have seen or heard anything that may help us solve any of these robberies then please get in contact.

“Also if you have been offered jewellery for sale in suspicious circumstances please let us know.”
