Sydney police divers continue search for pregnant woman

Police divers are continuing their search for a pregnant woman who disappeared from a boat moored at a northern NSW marina.

The 37-year-old was last seen by her husband on Saturday night leaving the boat, which was moored at a hotel marina on Wharf Street at Tweed Heads.

Police believe she exited the wharf through a security gate leading to the public car park area, and intended to use toilet facilities in the hotel.

An extensive search of the area included police divers checking surrounding waters.

Police divers from Sydney will join the search this morning.

Investigators hold grave concerns for the woman's welfare due to her pregnancy, the proximity to water and the fact that her disappearance is out of character.

She is of Indian descent and 170cm tall, with a medium build, dark brown complexion and black hair.

She was last seen wearing grey tracksuit pants, a black top and silver slip-on shoes.
