A woman who lives on Brae Avenue was said to have been left "shaken" after the incident when a man turned up at her home, on March 25, to ask if she would like her drive paving.
She said no and he left - but returned about half an hour to ask aagain.
She again said no, but a second man then appeared and pushed her over into the hallway. He then tried to remove her gold necklace before both men ran of towards an alleyway at the top of the road.
The woman suffered minor injuries to her neck and face.
The man who knocked on the door is described as white and about 5ft 9ins tall, wearing a brown hooded top and black bottoms.
Investigating officer Detective Constable Cressida Jewell said: "The victim was understandably shaken by what happened and we have been conducting various enquiries to locate the suspects.
"It is possible that this man may have called at other houses in the area and I would ask anyone who may recognise him to contact us."
Anyone who recognises this man is asked to contact DC 3128 Jewell at Bradford District CID on 101, quoting crime reference 13170135768.
Information can also be reported anonymously to the independent charity Crimestoppers on 0800 555111.
