A vulnerable 14-year-old boy with severe autism who police say is not streetwise and has no sense of risk or danger, has gone missing.
David Whyte was last seen at around 2am this morning at his home in Bridge Road, Hounslow.
He is unable to speak because of his autism, so he communicates through mobile phone apps.
David is described as black, approximately 5ft 5in and with black hair.
Police said he likes travelling on the transport network and when he has previously gone missing, has been found on buses and trains.
He was last seen wearing blue jeans and a red hooded top.
Anyone who has seen David or knows where he is should call police on 101 or Missing People on 116000.
