A woman was tied up and had a pillow put over her face during a burglary in Stoneygate Road on Friday.
Two men forced their way into the house at 12.50am through the back door and woke the 55-year-old resident.
They tied her wrists up and placed a pillow over her face while they searched the property.
A large quantity of Asian gold was taken during the incident and the offenders left the scene in an unknown direction.
The victim managed to raise the alarm and police are investigating.
One of the burglars is described as a man, possibly African, about 6ft tall and 32 years old.
Det Con Scott Hannam is keen to trace anyone who may have seen any suspicious activity in the area recently or anyone who is offered Asian gold for sale.
Det Con Hannam said: “I would ask local residents to be extra vigilant and report any suspicious people they see in their area to the police, immediately. Anyone who saw or heard anything suspicious in the Stoneygate Road area during the early hours of Friday morning is urged to contact the police as they may have vital information that could help this investigation.
“It is important that anyone who has jewellery in their home, whether it be worth a lot of money or be of sentimental value, takes the appropriate precautions and help discourage any further offences of this nature happening. Keeping it out of sight and locked away somewhere safe. This is one of the easiest things you can do and will help save the heartache of losing something that is precious to you.”
