Police are looking for two men they said zip-tied two other men Saturday in Queens during an attempted robbery, during which a woman who was also in the home went into labor.

It happened at an apartment near 123rd St. and Liberty Ave. in Richmond Hill around noon Saturday.

Police said the perpetrators took out a gun and tied up a 56-year-old man and a 29-year-old man with zip ties but fled without taking anything.

Investigators said a three-year-old girl and a five-year-old boy were also in the home at the time, along with the pregnant 27-year-old woman, who was taken to a local hospital in stable condition after she went into labor.

Everyone else who was in the home is in stable condition as well.
