Police have launched an investigation into an altercation that marred last Friday night’s harness racing at Bermuda Equestrian Centre.Police were summoned to the Devonshire facility after a fight broke out among rival drivers over a dispute.The incident is believed to have lasted some 30 minutes, observers claimed.“Around 10:30pm on Friday, September 20th police officers attended a reported dispute at the National Equestrian Centre on Vesey Street in Devonshire,” a police spokesman told The Royal Gazette. “Apparently two men had a minor altercation at the venue. Inquiries are ongoing.”Driving Horse and Pony Club (DHPC) President Arnold Manders did not return calls to this newspaper yesterday.The incident arrived fresh on the heels of another that marred the sport the previous week when it is alleged a man threatened association President Mr Manders with a machete during a heated row.The altercation was broken up before police arrived on the scene and no charges were pressed.After reviewing the incident DHPC officials determined that they did not have the authority to impose disciplinary sanctions on the man alleged to have threatened Mr Manders.“Our hands are tied because the individual is not a member,” Mr Manders said in a previous interview. “If it was a driver or member we could’ve dealt with it.”DHPC officials have refered the matter to Bermuda Equestrian Federation (BEF) who will ultimately determine what action, if any, to take.“The Bermuda Equestrian Federation are the ones responsible for the property so we have to turn it over to them,” Mr Manders said. “It has to be dealt with by them.”
