Every day, police officers respond to reports of all sorts of events and nonevents, most of which never make the news. Here is a sampling of lesser-known — but no less noteworthy — incidents from police log books (a.k.a. blotters) in our suburbs.

ONE MAN’S TRASH IS ANOTHER MAN’S TREE HOUSE

On Jan. 28, Acton police were sent to check out a report of suspicious activity: To the caller, at least, it appeared someone was living in a tree house. Officers quickly determined that the report was wrong on both counts: First, there were no squatters in sight, and second, the structure wasn’t even a tree house. It “turned out to be illegal dumping of some construction materials,’’ said Deputy Chief Richard Burrows, “not a squatter.’’

ROGER THAT

Just before 11 a.m. Feb. 8, Milton police received a call from a resident of Lantern Lane who reported that someone had rung her doorbell and left a walkie-talkie on her front porch. Not exactly manna from heaven, but officers retrieved the unexpected gift and brought it to the station.

DESPERATELY SEEKING A CELLPHONE CHARGER

At 6:51 p.m. Feb. 20, Marblehead police received a call from a resident who reported that a man came to his door and asked if he could come in and charge his mobile phone. The caller told police that the man appeared to be in his 40s and was wearing a blue peacoat, khaki pants, and a hat. The caller described his demeanor as “pushy.’’ Four minutes later, the same guy walked into the police station and asked officers to charge his phone. He told police he was from Swampscott, and when queried about the complaint lodged against him, he said, “I’ve been to several other houses and no one else has called you guys.’’ Did he think it a tad unusual for a stranger to approach residents and ask them to recharge his phone? “Nope,’’ he replied. And no, he said, he hadn’t asked to enter anybody’s home. Police declined to charge his phone, asked him to stop making that request of residents, and pointed him to the nearest bus stop. But hey, he knew just where it was: As he told officers, he’d been working in Marblehead for a decade.

RELIVING HIS GLORY DAYS

At 8:33 p.m. Feb. 20, Beverly police received a report of a stranger knocking on the door of a triple-decker on Simon Street. In three minutes, police arrived at the scene and learned that the unexpected visitor was a former resident “feeling nostalgic’’ who wanted to visit his family’s old apartment. Police terminated his walk down memory lane and sent him home in a taxi.

MORE SIGNS OF THE TIME

Political signs supporting Donald Trump this endless campaign season have been targeted by vandals before; we’ve previously reported how two Trump signs in Newton were spray-painted in September and one in Hull was set ablaze in January. Yet another Newton incident occurred March 8, when an officer was dispatched to Mague Avenue. A resident there told police that sometime between 7 a.m. and 4 p.m., three Trump campaign signs had been removed from the property.

CANINE PAPARAZZI

Just after 10 a.m. March 9, a woman contacted Stow police. She was concerned, she said, because her neighbor kept taking pictures of her dog. And not just any pictures, she said: The neighbor kept approaching the dog, and only seemed to snap pictures when the creature was barking. Police told her that taking photographs on a public way was not a crime, but documented the incident in the log for future reference.

MYSTERY SOLVED

At 4:39 a.m. March 1, Hopkinton police received a 911 call from a resident who feared that someone might be in her house. Officers responded and found something making a strange noise, all right: a Mylar balloon being pushed around by a fan.

ANOTHER FALSE ALARM

At 4:06 p.m. March 6, a Salem police officer was dispatched to investigate a report of suspicious activity. A woman told the officer “some suspicious things [had been] happening around her house’’ on Memorial Drive. Take, for example, the broken glass in front of her home. Upon closer inspection, the officer determined that it was not glass, but rock salt.
