Writing on Facebook, Brandywell Greyhound Track: “Folks, due to acts of vandalism we have had to take the decision to cancel tonight’s race meeting.
“In the 48 years of our operating history we have never had to abandon a meeting due to vandalism.
“We would ask those involved in this antisocial behaviour to think of the negative impact this has on our patrons of which this may be their only source of social interaction throughout the week.
“We welcome all and are open to working with those involved to include them in our sport and show them what a positive impact it has for all our patrons.”
The owners of the race track, Derry City and Strabane District Council, said there had been “a number of recent incidents at the site”.
“The Ryan McBride Brandywell Stadium and Brandywell Greyhound Track are there for everyone to use and enjoy and incidents such as this are an attack on the community,” a DCSDC spokeswoman said.
