Police received a call at about 9.30pm on Monday (June 19) about the alleged potential abduction.
Officers received a call from a woman who reported seeing a man being forced into the rear of a black car at the junction of Broadstone Way and Knowles Lane in Holmewood, Bradford.
The car, which is believed to have been carrying four males, is then reported to have made off in the direction of Farway.
Several other witnesses who reported seeing a similar incident were identified by officers.
The man involved is described as being of South Asian or East Asian descent.

"An extensive investigation is underway to establish the full circumstances, and I would ask the people involved, anyone who witnessed this incident or anyone who has any information, to please get in touch with officers."
