The Manhattan district attorney's office says a preliminary test for alcohol and drugs on one of the drivers involved in a tour bus collision in Times Square that injured more than a dozen people has come back negative.
The DA's office released a statement saying it will not make a decision to prosecute the driver until it completes its investigation.
"Preliminary testing for alcohol and drugs has come back negative. We are awaiting results of the full toxicology report. We are taking this matter seriously and prosecutors in the Office's Vehicular Crimes Unit are conducting a thorough investigation," the statement reads, in part.
Police had said that William Dalambert, 58, of Irvington, N.J. was driving while impaired, but they had said alcohol was not involved.
The accident happened around 3:30 p.m. Tuesday, when police say a CitySights bus and a Gray Line bus collided on 47th Street and Seventh Avenue.
More than a dozen people were injured.
