Police are growing increasingly concerned for the welfare of a missing Watford man.

Thirty-one year old Samuel Brett was last seen in the early hours of Saturday, May 16 in central Watford.

Mr Brett is described as white, around 5ft 10ins tall and of large build.

He has collar-length brown hair and a long brown beard, as well as a full-sleeve tattoo on his left arm, which is of coloured roses.

He may be wearing a maroon Fred Perry polo shirt and green Nike trainers.

It is believed he is either wearing blue jeans or grey and white checked shorts and a blue and olive rain coat.

Anyone who sees him or knows of his whereabouts is asked to contact police via 101.
