A Syrian asylum seeker is set to be deported from Sweden after a shocking video showed him pushing a 91-year-old woman down a flight of stairs in an attack that is set to reignite the country's debate over migration.

Karam Kanjo, 26, was caught on CCTV assaulting the elderly victim as she made her way to her husband's grave on August 29 this year.

Footage showed Kanjo - who entered Sweden during Europe's migrant crisis in 2015 and was on parole after raping another woman - grabbing his elderly victim on a flight of stairs in Sollentuna station, eight miles northwest of Stockholm.

The victim is seen struggling before the pair tumble down the stairs as he grips her necklaces, causing the woman a number of injuries. A witness to the attack is seen running for safety, leaving the elderly woman behind.

After the pair roll to the bottom of the stairs, Kanjo stands up and yanks her chains from her, before calmly walking away and leaving the elderly woman lying on the ground as two female commuters run down the stairs to assist her.

According to court documents obtained by MailOnline, the necklaces were gifts she received more than 40 years ago.
