Detectives investigating an aggravated burglary say they have received several calls after the crime featured on the BBC programme Crimewatch.
A reconstruction of the Bradwell burglary appeared on the programme on Tuesday night, July 12.
Det Sgt Tim Nye said several viewers had been in touch and provided the investigation team with numerous new lines of inquiry.
He said: “We’re pleased that the appeal generated several calls. One caller suggested a suspect which we will investigate further.
“We very much believe that the answer to this crime lies locally. Someone in the local area will know who carried out this burglary and I hope that new information will continue to come in.”
A 66 year-old woman was upstairs at her home in Netherside, Bradwell, at about 6.30pm, on Wednesday, February 23, when she realised a man was standing behind her, holding a knife.
He threatened her and she ran past him and down the stairs. He followed her and punched her in the face before running off. He had stolen cash from the house.
The victim, who suffered bruising to her arm, a cut lip and pain to her face, called the police.
She described the robber as white and of slim to medium build. He wore a black balaclava and a long sleeve, grey sweatshirt with white writing on the chest.
Police arrested two men, aged 19 and 18, in connection with the incident but they were later released without charge.
Anyone with information should call police on 0345 123 3333 or Crimestoppers on 0800 555 111.
