Indiana State Police at the Lowell Post said Zachary Keilman, 18, of Rensselaer walked into the post about 2 p.m. Thursday and told Sgt. Alan Jamerson he believed there was a warrant for his arrest, The (Merrillville) Post-Tribune reported Monday.
Keilman rolled up the sleeves of his shirt and showed Jamerson there were handcuffs on his wrists with the middle chain cut.
Keilman said he had been detained by a Newton County sheriff's deputy while attending a party with alleged underage drinking and had escaped the deputy's car while other party-goers were being questioned.
However, Keilman said he later realized he had left his identification in the deputy's car.
Keilman, who was taken to the Newton County Jail and released on bond Friday, faces a felony count of escape and a misdemeanor count of resisting law enforcement.
