Hong Kong police have launched a search for a father and his 11-month-old son, who have been missing for nearly two days.

The force renewed its appeal for information on Wednesday, with the Sham Shui Po district crime squad taking over the case.

“Police are urging residents to come forward with information about a man and his son reported missing in Sham Shui Po,” a spokesman said.

The force shared photographs of the 37-year-old Indonesian father, Mukit Alam Pratama, and his son, Mukit Shznjz Putra Pratama.

The man is described as about 1.75 metres tall, of medium build and weighing around 80kg. He has a pointed chin and short black hair.

He was last seen wearing a yellow down jacket, black trousers and trainers, along with a black cap.

The baby was reportedly last seen wearing white overalls. The family reported the pair missing on Monday afternoon.
