Police have issued an urgent appeal for information about a man who has gone missing with his 12-week-old son.
Nathan Hamilton, 24, who uses the nickname Chase, was last seen at about 10.30am today in Mistley, near Manningtree in Essex.
He was carrying the baby boy.
Mr Hamilton is black, 5ft 10in tall, of slim build, has short Afro hair and sometimes wears glasses. He was wearing a grey Converse tracksuit.
The baby was dressed in a blue t-shirt, a grey cardigan, Chino-style baby trousers and bootees.
It is thought the father and son went to Mistley station and travelled by train to Colchester or London.
Police say they are growing increasingly concerned for their welfare and have urged anyone who has seen them to call 999 immediately.
