Terrifying moment bearded man ‘kidnaps’ petrified woman banging on a stranger’s door begging for help before he drives off with her

Terrifying video captured by a home-security camera is helping police piece together the ‘possible kidnapping’ in suburban Portland as they announced today they had arrested the suspect.

The shock footage shows the woman ringing the doorbell of a stranger’s home near Southeast 32nd Avenue and E. Main Street as a man charges her from behind.

She is heard calling out ‘please help me! Please help me!’

The suspect then appears to drag the woman back to a white pickup truck before joining the traffic and driving off into the night.
