'There were two youth on motorcyles and a woman in an autorickshaw. The woman, assisted by the youth, forcibly shoved the army officer into the autorickshaw and sped away,' a witness told police.

Col. Kakoty was in Guwahati on way to Tezpur in Assam to join his new assignment after being transferred from Jammu and Kashmir.

'We are investigating as to who this woman is. We have to look into various angles and find out if the army officer and the woman had any relationship,' the police officer said.

Col. Kakoty is married with two children.
