A 28-year-old Westminster man was critically injured in Sykesville on Sunday in a dirt bike accident, according to the Carroll County Sheriff's Office.

Officials said that at about 5 p.m., deputies and rescue personnel from the Sykesville Volunteer Fire Company were called to Poole and Cherrytree roads in the northern part of Sykesville west of Route 32 for a report of a motor vehicle crash, and found a Yamaha dirt bike on the southbound shoulder.

Officials said they believe the driver was traveling south on Poole Road and lost control, causing him to be ejected off the dirt bike.

He was identified as David Anthony Wein, 28, of Westminster.

Officials said he was flown to the University of Maryland Shock Trauma Center with life threatening injuries, and was in critical condition. Officials said the driver was not wearing a helmet, and speed may have been a factor in the crash.
