Conor McGregor's popular bar in Ireland was attacked Wednesday night -- reportedly being hit by Molotov cocktails -- and now, cops say they're on the hunt for suspects.
According to The Sun, criminals threw two petrol bombs at McGregor's The Black Forge Inn in Dublin last night, and also left two pipe bombs near the watering hole's entrance as well.
A rep for McGregor tells TMZ Sports the UFC superstar was NOT inside of the building while it all went down. No word yet if he was an intended target in the attack.
"No one was impacted," the rep said, "and the pub is open and busy as always."
Ireland authorities confirmed to TMZ Sports there was "an incident of attempted criminal damage" near the Dublin pub ... but, thankfully, they added, "No damage was done to the premises."
Cops said they're now searching for any leads, and are urging any witnesses with video to contact them ASAP.
McGregor -- who bought The Black Forge Inn over two years ago -- has been spotted at the bar several times this month ... even posting footage from inside of the venue just hours before the attack happened on Wednesday.
