Updated at 5.00pm: Surgeons on Monday managed to successfully reattach one of two fingers severed from a toddler's right hand after he slipped on an escalator in Tsim Sha Tsui, according to the boy's mother.

The two-year-old is now in stable condition. His middle finger was reattached during surgery. However, doctors at the Queen Elizabeth Hospital failed to sew his fourth finger back on.

The boy was with his parents and younger sister when he slipped and caught his two fingers on an escalator handle in the basement of Star House in Tsim Sha Tsui on Sunday, news reports said.
