Detectives investigating two alleged assaults in Sheffield are renewing their appeal for witnesses.
The incidents occurred shortly after each other in the Collegiate Crescent area of the city at around 8.30am on August 2.
In the first incident, an unknown man is alleged to have inappropriately touched a woman before fleeing the scene. A short time later, a woman was injured after being assaulted by an unknown man.
On both occasions, the man is believed to have dragged the women to the ground but both women have shouted for assistance and have been approached by the public, which has caused the man to flee.
Officers are linking the incidents and additional police resources are in the area.
Detective Inspector Richard Partridge, leading the investigation, said: “I am seriously concerned about the actions of this man and the risk that he poses.
“We believe these assaults have a sexual motive, so we’ve increased the visible policing presence to reassure the local community.
“While thankfully neither woman was seriously hurt, we are urging anyone with information to come forward. This includes any information about incidents of a similar nature that may have occurred previously.”
The suspect is described as being a black man, possibly aged in his 20s, wearing dark clothing.
A 34-year-old man has been arrested and bailed in connection with the incident.
Anyone with information should contact 101 quoting incident number 351 of August 2.
