Three men forced their way into a woman’s home in Brighton and attacked her at knifepoint on Monday night (9 December).
The men wore scarves to hide their faces and demanded money after they barged their way into the flat in Upper Hollingdean Road at about 10.30pm on Monday.
They pushed their 25-year-old victim to the floor and one of the men pinned her down while the other two searched the flat.
They stole her iPhone and cash before leaving and running off.
The first man was described as black, 25 to 30 years old, muscular, 5ft 5in tall, with a shaved head and a flat nose. He was wearing a black jacket, black jogging bottoms and a black snood.
The second man was described as white, in his early twenties, muscular, 5ft 7in tall and with blondish short cropped hair. He was wearing a black long-sleeved top, black trousers and a black scarf around his face.
The third suspect was described as a white man, in his early twenties, 5ft 11in tall and slim. He was wearing a black jacket and a scarf around his face.
Detective Sergeant Cheryl Lewendon said: “This was a nasty aggravated burglary and a frightening ordeal for the victim who fortunately was not hurt.
“Anyone who has information is asked to come forward and speak to police.”
Anyone who can help is asked to phone Sussex Police on 101 or email 101@sussex.pnn.police.uk.
