Two homes in West Quincy were broken into in separate ­incidents one minute apart Saturday night, police said.

“They don’t seem to be related in any regard,” said Quincy Police Sergeant Michael O’Shea. “It’s a pretty busy area, but I wouldn’t say this is normal.”

A home at 175 Centre St. was broken into at 11:27 p.m. by two males, one of whom had a gun, O’Shea said. The resident suffered a head injury “from an altercation with the suspects,” O’Shea said. The resident was taken to a hospital with non-life-threatening lacerations, he said.

“It is unknown what [the suspects] were looking for,” O’Shea said.

In a separate case, another male broke into 319 Granite St. around 11:28 p.m., about a half-mile from the first break-in, but fled after a resident started yelling, O’Shea said.
