LEWISTON — The downtown was rocked Thursday morning by a pair of shootings reported nearly eight hours apart.

The first report came in shortly after 3:30 a.m., police said, when shots were heard in the area of Walnut Street.

Just after 11 a.m., more shots were reported on Pierce Street, where police found a truck with a window that appeared to have been shot out.

By 9 p.m., no arrests had been made.

Nobody was hurt in either incident, but the blasts rattled the downtown as police fanned out in search of suspects.

One man who works in the area said that at about 3:30 a.m., he went outside where he found police with rifles searching the streets. He had heard fireworks hours earlier, the witness said, and had assumed that the latest blasts were more of the same.

Police were still investigating that incident at about 11 a.m. when a man called to report that a window had been shot out of his pickup truck on Pierce Street. Once again, officers scrambled to the location, cordoning off the area, questioning witnesses and searching for suspects.

Police were given a description of a red Cadillac that may have connected to the reported shooting, investigators said.

They stopped a vehicle matching that description on Main Street shortly after officers arrived at the scene on Pierce Street. Over the next few hours, police said, officers stopped several red Cadillacs, but none appeared to be connected to the shooting.

A section of Pierce Street was cordoned off at about 11:30 a.m. as police searched for evidence related to the reported shooting.

Surveillance cameras in the area were checked for information.

The morning shootings were not the first this month in the downtown area. On Nov. 4, shortly before 10 a.m., shots were fired into a car on Sabattus Street, near Main.

Days later, police arrested Jauston Sanders, 24, of 195 Lincoln St. who reportedly told police he had shot at a man in a car from a rival gang because he had been “disrespected.”

The car, a Chevrolet Impala, had four bullet holes on the passenger side and one through the windshield, police said. The bullet through the windshield lodged near the headrest and would have just missed driver’s head. Police recovered six shell casings from a .40-caliber gun where the shooting was reported.

Sanders remained jailed Thursday night on a charge of attempted murder.
