This year’s South Boston St. Patrick’s Day parade started earlier to curb last year’s public drinking and violence, which led to 11 arrests.

The Boston Police Department has announced that 9 people have been arrested, with 4 people being summoned to South Boston District Court following South Boston’s Saint Patrick’s Day parade.

The Boston Police Department issued a warning ahead of St. Patrick's Day and the South Boston St. Patrick's Day Parade on Sunday, urging people to watch out for spiked drinks and urging those who've consumed spiked drinks to report the incidents to police.
