A post-mortem examination on the body of 14-year-old Alice Gross has proved inconclusive.

Police say further tests need to be carried out to establish exactly how the teenager died.

Alice went missing on 28th of August - her body was recovered from the River Brent in west London on Tuesday.

The post-mortem began yesterday but continued today due to the “complex nature” of the investigation, a police spokesperson said.

Police are treating the investigation as a murder inquiry.
