A 70-year-old Canadian man was so annoyed when an Amber Alert phone message disrupted his rest that he called 911 — and now he’s been arrested, according to a new report.

Niagara Regional Police issued the missing-child alert Tuesday afternoon after five kids went missing, CBC reported.

But the grumpy old man didn’t seem to care about the reason, Hamilton Police told the CBC.

He aired his grievances to a 911 operator just after 5 p.m. Tuesday, a few minutes after the alert was issued, said Hamilton Police acting Detective Sgt. Lisa Chambers, to the network.

“Simply put, he was angry about receiving the Amber Alert on his phone because he was trying to rest,” she said. “And then he further told us he would continue to call in response to the ongoing alerts.”

Investigators were able to identify the caller, arrest him and charge him with mischief. His court date is set for Oct. 15.

The children were found safe Wednesday, and authorities credited the alert with providing information that led to their discovery, according to the report.

“It’s very frustrating,” Chambers told the outlet. “I never thought the day would come where I’d have to explain to an adult the importance of not tying up a 911 line and the importance of an Amber Alert … in locating a child who may be in danger.”
