According to TMZ, prosecutors claimed a homing pigeon was killed by a dolly while Bay was filming in Rome, where harming or killing wild birds is illegal.
They also claimed a person on set photographed the bird and alerted officials.
Sources, however, told TMZ all pigeons landed safely during filming.
One also said:
"Everyone knows Michael is an animal activist. This would never happen on his set."
"There are dozens of witnesses who said that this didn't happen."
Many on Twitter sided with Bay, and several pointed out—if it did actually happen—it was likely an accident.
Some also stated it's not a big deal given the pigeon population in many areas of the world, but each and every pigeon is protected in Italy.
It seems the majority, however, took to Twitter to entertain the idea the alleged avian tragedy transpired in true Bay fashion.
While Bay is not being accused of killing the pigeon himself, he is being charged because he was the director on the production.
Bay told The Wrap:
"I am a well-known animal lover and major animal activist."
"No animal involved in the production was injured or harmed."
"Or any other production I've worked on in the past 30 years."
Bay had the option to pay a fine, but he refused to plead guilty to injuring an animal.
