Detectives looking for missing schoolgirl Alice Gross have arrested a man on suspicion of murder.

The 14-year-old, of Hanwell, west London, was last seen near the Grand Union Canal on Thursday 28 August.

She had recently been diagnosed with anorexia, her mother said.

Police said the suspect was arrested following information received by detectives on Saturday and was in custody at a west London police station.

A spokesman said: "All lines of inquiry are still open at this time and this remains a missing person investigation at this stage."

Cyclists appeal

Police divers are continuing to search the canal where Alice was last seen 10 days ago.

The Brentside High School pupil left the family home at 13:00 BST on 28 August. She had told her family she was going to meet some friends and would be back that evening. Instead she went for a walk alone along the tow path.

She was captured on CCTV cameras at 14:23 near the Holiday Inn at Brentford Lock, heading towards Kew, and again at the same location walking towards Hanwell at 15:45.

She was then recorded by CCTV at 16:23 near Trumpers Way Canal Bridge.

Earlier police appealed for five cyclists who rode past Alice near Trumpers Way Canal Bridge to contact them.

Her purple rucksack was found on Thursday 4 September near the River Brent.

Alice was described as being 5ft 2in tall, slim, with shoulder-length light brown hair.

When her family last saw her, she was wearing dark blue jeans, a dark green lacy cardigan and denim Van's shoes. She may also be wearing tartan-framed spectacles.

The CCTV footage, released earlier this week, showed she had taken her cardigan off and was wearing a dark grey T-shirt.

Alice's mother Rosalind Hodgkiss said: "We are desperate to know that she is safe and we really want her to know that we want her home, and we are desperate for her to know how loved she is."
