911 dispatchers received a call around 4:30 a.m. Thursday from two women saying they heard muffled cries from help coming from the trunk of a car they were riding in earlier. The driver, a man in his 20s, reportedly told the women it was his dog. The women called police as soon as they were able to get to a phone.

Three hours later, a man walked into the Patrol East police substation and told authorities he had been kidnapped and locked in a trunk for hours overnight. Police say he did not appear to be injured, though his wrists did look as though they had been tied together at one point.

About one hour later at 8:45 Thursday morning, police pulled over a car in the 1500 block of N. Spruce Street. Police said the driver jumped from the car, ran several blocks, and tried to hide in a nearby vacant home. A dog in the police canine unit was able to hold him in place until police arrived.

Authorities said they arrested the man on suspicion of kidnapping. Police do not believe the man held in the trunk was targeted at random. In fact, relatives of the suspect say the two men are friends and had visited together the night before. How the victim came to be locked in the trunk, how many hours he was there, and how he regained his freedom are still not clear tonight.

Police spent much of Thursday interviewing witnesses, the victim and the suspect. They say more information may be available Friday morning.
