New York ( CNN ) -- Prosecutors say for now , they wo n't be charging the driver of a double-decker tour bus that collided with another bus in Manhattan 's bustling Times Square Tuesday , injuring more than a dozen people . Police initially charged William Dalambert , 58 , of Irvington , New Jersey , with driving while impaired , but preliminary tests did not show any drugs or alcohol in his system . So , Manhattan prosecutors declined to file charges `` until we we have completed our investigation , '' Joan Vollero , a spokeswoman for the district attorney 's office , said Thursday . He has been released . `` We are awaiting results of the full toxicology report , '' she said . `` We are taking this matter seriously and prosecutors in the Office 's Vehicular Crimes Unit are conducting a thorough investigation . '' Dalambert was driving a bus that struck another double-decker bus on Seventh Avenue , police said . At least 13 people were injured , one seriously , after the two tourist buses that traverse city neighborhoods collided about 4 p.m. Tuesday . The crash occurred near a normally packed sidewalk next to the TKTS booth at 47th Street and Seventh Avenue at Times Square , police and fire officials said . Authorities said a preliminary investigation revealed that a Gray Line double-decker tour bus , driven by Dalambert , was traveling southbound on Seventh Avenue and sideswiped a City Sights double-decker tour bus and a GMC Yukon , also traveling southbound on Seventh . The collision caused the Gray Line tour bus to go up on the sidewalk and strike a traffic light pole , which fell to the sidewalk . Investigators have clear video showing a bus closest to the sidewalk speeding through the intersection and striking an SUV and another bus that just passed the intersection , according to a law enforcement official who saw the video . The driver of that bus claimed he was having brake issues , the law enforcement official said . But an examination of the bus revealed no mechanical problems . By all accounts , the collision could have been worse . Earthcam video from the scene showed pedestrians running from the crash site moments before a towering pole crashed to the sidewalk , appearing to strike a man in the leg and narrowly missing his head . A fire official at the scene said the number of injuries was surprisingly low , given the size of the pole . Times Square is a popular launching spot for the ubiquitous double-decker buses , which take tourists around Manhattan . After the accident , dozens of tourists stood at what is sometimes called the `` Crossroads of the World , '' taking pictures and video of the crash scene . CNN 's Ray Sanchez , Marisa Marcellino and Donovan Long contributed to this report .
Preliminary drug and alcohol tests on bus driver came back negative , prosecutors say . At least 13 people were injured when two tour buses collided in New York 's Times Square . Prosecutors declined to charge driver William Dalambert pending further investigation . Police had earlier accused Dalambert of driving while impaired .
