Officers attended but the van had already driven off in the direction of the police station.
The passenger in the van was wearing a red T-shirt, the driver was not seen.
Detective Chief Inspector Jim Reeves, said: "The caller was concerned that someone in the back of the vehicle was in danger and called us.
"We are investigating further to trace the occupants of the van and establish exactly what happened.
"We believe the van is a Mercedes Sprinter size panel van or similar, and I would urge anyone who saw the van in Alma Road or has any information which may help with the enquiry to contact me.
"It could be the case that this is all completely innocent and no crime has occurred, however we need to trace the van to confirm this and I would urge the occupants to contact us so we can clarify exactly what happened."
