Police are investigating robbers on bikes who have three times targeted women leaving or going to factory work.
The incidents took place in Sutton Bridge last night and last Thursday, and in Long Sutton on Mondon morning.
Each time the victims have seen that the male robbers have had a knife.
At about 10.35pm on Thursday, two females (age 23 and 25) were walking to work along Chalk Lane towards Millennium Way in Sutton Bridge when they were approached by two males on bikes, who blocked their path and demanded the contents of the women’s pockets.
Although no verbal threat was made to use a weapon, the victims were able to see that both offenders were in possession of kitchen knives. The women handed over a mobile phone and some cash.
Shortly after 6pm on Monday, a 23-year-old woman left work at one of the factories and began walking home along Bridge Road, Long Sutton, when she was approached by three males on bicycles. One stopped in front of her and demanded money. He was holding a kitchen knife.
When the victim said she had no money, he asked for her phone and she handed over a black Sony Erickson Neon touchscreen phone and a white mp3 player.
The offenders are described as in their late teens, English speaking and one was wearing a light coloured T shirt. The offender with the knife was wearing a grey hoody, black jacket, jeans and trainers.
Later on Monday evening, at about 10pm, a 23-year-old woman leaving work in Sutton Bridge, crossed the bridge over the river and was approached by males on bicycles who asked for a light.
One produced a knife and asked her to empty her pockets but she threw a cigarette at them and ran off.
Det Insp Dave Rimmer, from Spalding CID, said: “This type of offence is extremely rare in this area and I am very keen identify and arrest the offenders.
“I believe them to be local to the area and, as such, I am appealing to the communities of Sutton Bridge and Long Sutton to help the police identify them.
“I would urge anyone who has any information to contact Lincolnshire Police on 101 or Crimestoppers, in complete anonymity, on 0800 555 111.”
