An elderly man has been attacked by four men at his Mapperley home.
It is believed that cash and jewellery were stolen during the incident, which took place in Plains Road at about 6pm on Friday.
The burglars, who covered their faces, are believed to have made off in a silver Mercedes a short time later.
Detective sergeant Georgina Ball said: "We need to hear from anyone who was in the area at the time, did you see anything suspicious? These offenders have terrified this elderly man in his own home and left him in shock."
