Police investigating the attack of a 45-year-old woman in Ipswich are renewing appeals for witnesses to come forward.
The attack occurred at 12.05am on Sunday 4 November on Stoke Bridge, near the entrance to the skate park.
The victim was walking over the bridge in the direction of the town centre when she passed another person walking in the opposite direction who appears to strike her with a single punch resulting in her falling to the ground.
The victim suffered a serious head and eye injury and is still suffering with the effects of the attack and requires ongoing medical treatment.
Detectives would like to hear from anyone who may have seen the suspect circled in red in the footage.
