Tell us about jewel thieves, say police
Police are concerned that people who have had jewellery snatched from them in the street are not telling them about the crimes.
Officers in Belgrave, Leicester, believe the crime is under-reported, hampering their efforts to find the thieves behind the attacks.
In the past fortnight, two people in the area have officially reported to police that they have had items of jewellery stolen.
However, two other people confided in officers this week that they were also targeted.
Inspector Ed McBryde-Wilding, commander of Keyham Lane police station, said his officers needed to hear about attacks as soon as possible.
Insp McBryde-Wilding said: "The people who are committing these offences will often come from behind and are disappearing into the distance by the time the victims can gather themselves. We think some people are assuming there's no point in reporting it to us because they can't give us descriptions.
"But we need people to report incidents like this. We can then analyse the pattern and put our resources in the right places.
"There is also potential CCTV evidence and my officers are conducting checks in the area which can help us find the people who are carrying out these thefts."
Pc Laura Nutt, whose beat covers Belgrave and Melton Road, said two people told her this week that they had been victims.
She said: "We have had male and female victims of all ages.
"We are constantly talking to people in the community to encourage them to tell us about these incidents, especially in the run-up to Diwali and Navratri, when Belgrave will be particularly busy."
A woman whose gold necklace was snatched earlier this year in the Melton Road area urged victims to come forward.
She said: "I did tell the police what happened to me. That is the right thing to do, because these people need to be caught.
"The police can only do that if people talk to them."
Assistant city mayor and local councillor Manjula Sood said there were plans to write to every household in the area to warn of the dangers and encourage people to tell police.
Coun Sood said: "It is very important that people tell the police about this, even if they cannot tell them what the person looked like. All information is important and can help the police find these people.
"We have to help the police catch the people who are committing the crimes."
