An attempted robbery and a separate theft Sunday at Suffolk Downs are being investigated, State Police said.
The two incidents occurred minutes apart and came toward the end of two days of live thoroughbred racing at the East Boston track.
Around 6:20 p.m. Sunday, a male suspect walked up to a teller window at the track, placed a bag down, and demanded the teller fill it with money, State Police said. The teller then notified another employee to contact security at the racetrack, and the man fled the scene leaving the bag behind.
Around 6:30 p.m., at a separate teller window, a male suspect took “a quantity of money” that had been left on a counter and ran away with the cash, State Police said.
Authorities searched the racetrack and stable and did not find a suspect in either theft.
Officials from the State Police Gaming Enforcement Unit, Boston police, and the Massachusetts Gaming Commission are investigating whether the thefts are related.
“The Gaming Commission is aware of the incident that occurred at Suffolk Downs,” Massachusetts Gaming Commission spokeswoman Elaine Driscoll said Monday. “Members of our State Police who are assigned to our investigation and enforcement bureau are working closely with the Boston police to further investigate the incident.”Ben Thompson can be reached at firstname.lastname@example.org.
