Two masked gunmen shot up a house with five people inside in Riverhead where the duo had committed a home invasion on Tuesday night, authorities said.

Two adults and three children—including two boys ages 15 and 12 and a 5-year-old girl—were in the East Avenue home when the gunmen broke in at 11:29 p.m., Riverhead Town Police said.

The victims called 911 after the suspects fled and started shooting at the house. None of the residents were hit by the gunfire.

The case marks the 12th armed home invasion in Suffolk in a six-week span starting Jan. 15. Two other cases involved shootings, including a Flanders home invasion that left a man dead and a Central Islip home invasion that left a shooting victim wounded.

Investigators found shell casings outside the house. Detectives are continuing the investigation.
