Tuan was last seen in Eastleigh at around 8.30am this morning, Sunday, 4 April.
We have conducted a number of enquiries and it is believed he may be in the Southampton area.
Tuan is described as Vietnamese, of skinny build, approximately 5ft 3in tall, has grade 1 black hair.
He was last seen wearing a three quarter length orange and yellow Superdry puffer jacket with a fur hood and black and white slider shoes. He was also wearing two gold rings on his left hand and a gold chain around his neck.
We are growing increasingly concerned for Tuan’s safety and are now asking the general public for help.
