Police are appealing for help tracking down a man who has been missing for nearly a month.
Marco Moniz, 24, of Valognes Avenue in Walthamstow, was last seen at Kings Cross Station at around 1pm on Tuesday February 5.
He was reported missing two days later.
Mr Moniz is currently on antibiotics and he does not have his medication with him.
A Metropolitan Police spokesman said: "Marco is from Portugal and has been in the UK for approximately four years.
"He is said to be able to speak enough English to get by."
Mr Moniz is described as dark skinned and approximately 5ft 8ins to 6ft tall.
He is slim with brown eyes and short, dark brown hair.
He has two tattoos, one on the centre of his right arm - which says 'Marco' - and one on the centre of his left arm with the word 'Moniz'.
