Police have released CCTV footage of two men wanted in connection with a sexual assault by suspects wearing Scream masks.
The images, released by Greater Manchester Police (GMP), appear to show two men walking near the Oasis Centre in Denton on Halloween shortly before the assault on a 22-year-old woman as she walked along Sunningdale Road in Haughton Green.
One of the suspects is seen wearing a Scream mask - made popular by the antagonist in the 1996 horror film of the same name, whose disguise was based on the work of Norwegian artist Edvard Munch.
Police said the woman was tackled by four people wearing the ghost-face masks, between 7pm and 7.20pm on October 31, but was able to struggle free and raise the alarm.
One of the men was said to be tall and wearing white trainers, while another was said to be of a chubbier build and in his early teens.
Detective Sergeant Dave Donlan said: "It is been more than three weeks since this woman suffered a horrible ordeal at the hands of four individuals who were dressed in Halloween-type masks.
"We are continuing with our inquiries to identify all those involved in the attack, and have now released CCTV footage of two men we need to speak to as part of our investigation. One of the men in the CCTV can be clearly seen wearing the Scream-mask used in the attack.
"I would urge anyone who recognises these two men, or the men themselves, to come forward as soon as possible.
"This woman went through hell that night and we need to find those responsible. Justice is the least she deserves. I would therefore reiterate that if anyone does know something, please come forward and talk to us, anonymously if needed."
