Police are looking for two men who they say tried to rob an apartment in Queens over the weekend.

The stress of the home invasion caused one of the victims to go into labor.

Investigators say the men entered an apartment near 123rd Street and Liberty Avenue in Richmond Hill around noon on Saturday.

They say the pair took out a gun and tied up a 56-year-old man and a 29-year-old man with zip ties then left the apartment without taking anything.

Investigators say two young children and a 27-year old pregnant woman were also in the home at the time, and the woman went into labor. 

She was taken to a hospital in stable conditon.

Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-8477, or text CRIMES and then enter TIP577, or visit www.nypdcrimestoppers.com.
