The incident is believed to have taken place at around 8pm on Monday.
West Mercia Police said the teenager was walking along Alma Avenue, Malinslee, when he was approached by four young men, believed to be in their late teens.
The force said the four took the boy by foot through the town centre to a flat near town where he was assaulted.
In a statement, officers said that the next morning the boy left the flat and ran towards Aldi in the town centre but was followed by his attackers who then took him to Telford Town Park.
Police said the attackers ran off a short time later and the victim was found by a member of the public at just after 9am.
Officers said he had suffered minor injuries during the incident and was treated at the scene by paramedics.
The attackers are described as black and in their late teens.
One of them was said to have been wearing a mask over his eyes.
Detective Sergeant Deborah Bentley said: “The investigation is in its infancy and officers are working hard to establish the full circumstances of this incident.
"We have taken a statement from the victim and we are conducting a full and thorough investigation, as the public would expect. We believe this to be an isolated incident and one line of enquiry is that the offenders may be known to the victim. We understand this will be very alarming to the local community and as such we have put additional patrols in the area for reassurance.
"If anyone heard or saw anything at any of the locations mentioned then we would like to hear from them. We’d particularly like to hear from anyone who was driving through the town centre on Monday evening or Tuesday morning and has a dash-cam fitted to their vehicle.”
