Avishay Cohen was hit by the driver of a van while rollerblading at Delancey and Ludlow at about 8PM on Sunday night. The 26 year-old Williamsburg resident is in critical condition at Bellevue Hospistal. Police have arrested a suspect, James Simpson, 57 year old, of Bedford-Stuyvesant. Apparently, Cohen was first hit by the van and then somehow he managed to get pinned underneath a taxi. A police officer said, ""It was horrible. What happened was crazy. I just couldn't figure out how he got pinned down there."
