Two women and a girl in her late teens were verbally threatened and then attacked in a vicious assault in east London which left one requiring plastic surgery.
Detectives investigating the incident said the group were walking past the New Fairlop Oak pub in Fencepiece Road, Ilford on May 14 this year when sexual comments were made toward the teenager.
After walking away from the men the women were then attacked, in the incident at 2.15am.
Police have now released images of two men they want to speak.
Detective Constable Amanda Mead said: “We think these men may have information about the attack on these women, one of whom now requires plastic surgery on her face following the assault.
“Various efforts are ongoing to trace these men, and we feel now is the right time to release their images.
“Both violence and its aftermath can be deeply traumatic and we are committed to tackling violence against women and girls in Redbridge.
