A New York City police department investigation has determined that employees at a U.S. fast food restaurant did not any commit criminal acts after three officers drank milkshakes that may have been tainted with bleach.

New York Police Department Chief Detective Rodney Harrison tweeted the announcement early Tuesday after a “thorough investigation” had been conducted.

The New York Patrolman’s Benevolent Association said in a statement three officers concluded “a toxic substance, believed to be bleach,” was added to their milkshakes at a Shake Shack restaurant in the borough of Manhattan.

The officers had been assigned to work at a protest against racial injustice that was sparked by the May 25 death of George Floyd in police custody in the midwestern city of Minneapolis.

They stopped at the Manhattan restaurant Monday evening in for a meal, according to the New York Patrolman’s Benevolent Association. 

The Detectives' Endowment Association said the officers were treated at a hospital but were not seriously injured.

Shake Shack tweeted it was “horrified” by the alleged contamination and said it was cooperating with police in the investigation.
