The cheque for the amount was presented to Dallas Mayor Mike Rawlings and Executive Assistant to Dallas Police Chief David Pughes, by the group of Indian-American community leaders led by A K Mago, founding chair of the US India Chamber of Commerce in Dallas.
Mago said they appreciate the protection police give them and they wanted to recognise what they do for the community every day.
Mayor Rawlings said this is more than generous and he has much respect for the Indian community.
About half the amount came from the US India Chamber and its members.
Other groups such as the Dallas Indian Lions Club, DFW Hindu Temple, the DFW Gujarati Samaj, the Karya Siddhi Hanuman temple, the Jain Society of North Texas and the India Association of North Texas, donated about $5,000 each.
On July 7, a sniper ambushed and fired upon a group of police officers in Dallas, killing five officers and injuring nine others.
