Detectives investigating the murder of 18-year-old Pield Heath House student Alfie Stone in Ickenham have arrested a woman. The 32-year-old was held on suspicion of murder after attending a west London police station.

A murder investigation was launched by the Metropolitan Police's Homicide and Major Crime Command after officers were called to High Road, Ickenham, at 5.35pm on 9 November following reports of a stabbing.

Stone, who attended Pield Heath House, an academy for young people with special needs in Uxbridge, was treated at the scene by the London Ambulance Service before being taken to a west London hospital where he later died. He became the 13th teenager to die from stab wounds in 2015.

Tributes were paid on social media to the teenager, whose post-mortem revealed he died of a stab wound to the chest. "Rip Alfie stone. u will be loved and missed by all and mostly ur family i will admit it will be hard for everyone," one read.

"My thoights [thoughts] are with u and ur family rip bro the angels and fairys [fairies] will look after you bro see u soon g love to the moon and back love you bro see u soon xxx," another friend said on Facebook.

A 27-year-old man was arrested on 9 November in connection with this incident and taken to a west London police station. He has been bailed to return on a date in mid-December pending further enquiries.
