Thieves forced open the front door of a house in Harvey Road on November 7 where they stole jewellery.
Among the items taken was a gold charm bracelet, a pearl necklace, a distinctive gold bracelet with rams’ heads on either end and a collection of other gold rings, including the victim’s wedding and engagement rings.
At about 2pm they walked out of the home, passing the victim on her way up the driveway.
The men were all dressed in blue fleece-like jackets and blue trousers and were aged 30 to 40. One had a round face.
They are thought to have escaped in a dark vehicle that was parked at the junction of Harvey Road and Southsea Avenue.
PC Louisa Tyler said: “The burglary happened in the middle of the day in a residential area where there are often vehicles and walkers coming and going.
“I’m hopeful that someone in the area saw the men involved or them getting into the vehicle to escape.
“Please contact us if you saw or heard anything, no matter how insignificant you might think it is. It could be of vital importance to my investigation.
“I would also urge anyone who is offered jewellery for sale at a low price to contact us. It may be stolen and if you buy it and we confiscate it you will not get your money back.”
