Several shots were fired at a building in Portland’s East Bayside neighborhood early Tuesday morning, the latest in an alarming uptick of shootings around the city, police said.

Residents reported hearing multiple shots around 1:30 a.m. in the area of Fox and Greenleaf streets. Officers found evidence that rounds had struck a second-story home on Greenleaf Street. They also recovered multiple shell casings from the area.

No injuries were reported and the incident remains under investigation.

Crime overall in Portland declined in 2020 and the downward trend has continued this year. But Tuesday’s shooting was the 10th incident involving gunfire in Portland since October 2020 and the third this month. While only one person was known to be injured as a result of the shootings, the uptick is deeply concerning, the department said in a statement.

Shootings have occurred in various parts of the city. The only report of an injury was a 19-year-old male who was shot twice in the arm on May 7, police said. In some other cases, officers found bullet holes in buildings or a car. In most cases, they recovered between two and 10 shell casings from the scene.

The shooting Tuesday is the third this month, police said.

Police said someone was seen firing a gun on a street in East Bayside after midnight on the morning of July 5. That incident took place after a large crowd gathered nearby and set off fireworks, although the gunfire was being investigated as a separate incident.

And at around 3:20 a.m. on July 13, someone fire a gun from a car on West Kidder Street in East Deering. Six shell casings were found there.
