Rizwan Dhanani was last seen around 2 a.m. on April 1 leaving a Dairy Queen in Auburn at 220 15th St. N.E., where he works.

Earlier, shortly after 1 a.m., firefighters responded to an explosive fire at a Redmond restaurant Dhanani reportedly owns, Celtic Bayou, at 7281 West Lake Sammamish Parkway N.E.
The blaze significantly damaged the restaurant. No one was injured. A man was seen leaving the area shortly after the fire. Investigators believe the blaze was intentionally set.

Redmond police say they are concerned for the well-being of Dhanani, a man who they say may have information on the fire. Police do not consider him a suspect in the arson.

Relatives of Dhanani told investigators they last heard from him around 11 p.m. on March 31, adding that he is without his usual vehicle, cell phone and jacket. His wallet was also found in the vehicle with his ID.

Dhanani is East Indian, about 5 feet 9, 150 pounds with black hair and brown eyes. He was reportedly last seen wearing a brown sweater, light-blue jeans and yellow tennis shoes.
