Police are looking for four men in their 20s who robbed an Aiea home that was found to be a marijuana growing operation.

Police said the men entered the home through an unlocked door at about 1:30 a.m. Sunday, armed with handguns, their faces covered and demanded money.

The people inside the home were three men, ages 24, 25 and 26 and a 30-year-old woman.

The men then took property from the victims including their cell phones and fled.

While police investigated the robbery, they found evidence of a marijuana growing operation inside the house, police said.

Narcotics vice officers were called and dismantled the operation, police said.
