An explosive that was slipped through a mail slot damaged a Mt. Washington heating and cooling business Monday night, according to Pittsburgh police.

The initial investigation began about 10:40 p.m. when police received a burglar alarm call at Boehmer Heating and Cooling on Hargrove Street, according to Public Safety spokeswoman Sonya Toler. About eight minutes later, she said, the business's fire alarm went off.

Fire crews responded but found no fire at the business, Toler said, and the business owners could not be reached.

Just before 11:30 p.m., the fire alarm went off again, she said.

Fire crews responded again and found a lot of smoke but no fire, Toler said. There was damage to the ceiling above the entrance. Crews determined there had been an explosion, she said.

Arson investigators and the bomb squad responded. Investigators believe that an explosive was slipped through the mail slot, Toler said.

No one was in the building at the time. An investigation continues.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.

While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.

We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.

We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.

We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.

We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
