The 32-year-old mother-of-two, in London for a weekend shopping trip, was attacked in the early hours of Saturday after she went for a stroll from her hotel in the King's Cross area.
She was followed by a gang of four black and two white youths, aged between 14 and 20. When she got to a canal footpath she was grabbed, stripped and subjected to sexual assaults.
After the attack the youths asked the woman if she could swim. When she said "no", they pushed her into the canal. The woman could swim and made her way to the opposite bank where she raised the alarm.
Detective Superintendent Keith Manktelow, a police spokesman, said: "It was an absolutely horrendous act of violence ... It's particularly disturbing that her attackers were so young."Reuse content
