A man wanted for kidnapping and dangerous driving in two separate cases is accused of speeding the wrong way and onto downtown sidewalks as he evaded police in a stolen vehicle, Calgary police said Tuesday.

Sheldon David Marcellus, 30, is wanted on 19 Alberta-wide warrants in relation to kidnapping, vehicle theft and dangerous driving. Anyone who spots him should not approach him and should call authorities immediately, police said.

During Tuesday's incident, a stolen 2008 Ford Explorer ran several red lights along Barlow Trail, reaching speeds of about 100 km/h. It was later seen near 36th Street turning onto 16th Avenue at a high rate of speed, ending up in the downtown core before speeding away, police said.

No one was injured in the incident.

"During the numerous times the vehicle was observed throughout the city, officers believed the driver matched the description of Marcellus that was put out earlier," said acting Staff Sgt. Kristie Verheul.

On Dec. 17, 2009, a man in a stolen Ford F-350 was seen driving recklessly, failing to stop for police and then hitting another vehicle before driving off, police said. That truck was later found in the North Hill Centre parking lot.

In an unrelated case on Dec. 21, 2009, several people are alleged to have kidnapped a man and assaulted him in a southeast Calgary residence. Investigators believe the incident was related to drugs.

The victim was able to escape the home and call police.

The suspect is described as five feet, seven inches tall, 150 pounds with a medium build, brown hair and hazel eyes. Police believe he is driving a stolen vehicle.
