An Uber Eats delivery driver, described by relatives as a hardworking Pakistani immigrant grandfather, was killed in a crash after officials said he was carjacked by two teenage girls in Washington, D.C.

The 13-year-old and 15-year-old, who have not been identified because they are minors, allegedly used a stun gun on the driver on Tuesday, causing him to crash his car, according to the Metropolitan Police Department.

When responders arrived at the scene, about a block from Nationals Park, they found the victim suffering from life-threatening injuries, police said. He was pronounced dead at a hospital.

Mohammad Anwar, 66, of Springfield, Virginia, was identified by his family as the victim, NBC Washington reported. He was working for Uber Eats at the time of the assault, according to relatives and Uber.

“He was a hardworking immigrant who came to the U.S. in 2014 to build a better life for himself and his family. The loss for his family is immeasurable,” the family said in a statement.

Uber offered its condolences to Anwar’s family in a statement.

“We are devastated by this tragic news and our hearts go out to Mohammad’s family during this difficult time,” the statement said. “We’re grateful the suspects have been arrested and thank the Metropolitan Police Department for their diligence with this investigation.”

Anwar is survived by a wife and two adult children in the U.S. and an adult son and four grandchildren in Pakistan, according to his family.
