Alice murder probe as body found

The hunt for the prime suspect in the disappearance of teenager Alice Gross escalated after search teams found a body in a river and launched a murder inquiry.

Convicted killer Arnis Zalkalns, who was spotted following the 14-year-old along a tow path when she was last seen, vanished nearly a month ago.

Scotland Yard has come under fire for delays in identifying the 41-year-old Latvian as a risk, and so far has not been able to apply for a European Arrest Warrant due to lack of evidence.
