Authorities say the owner of the exploded Michigan building was arrested at the airport while attempting to leave the US.

The owner of a suburban Detroit business that caught fire and exploded, resulting in the death of a man, was arrested at a New York airport as he was attempting to leave the country on a one-way ticket to Hong Kong. Noor Noel Kestou, 31, was apprehended by U.S. Customs and New York Port Authority personnel at John F. Kennedy International Airport and was brought back to Michigan to face charges.

Kestou, a resident of Commerce Township, was charged with involuntary manslaughter in connection with the tragic incident that took place on March 4. The explosion occurred at a Clinton Township building that housed a distributor for the vaping industry called Goo, where over 100,000 vape pens were stored. The explosion sent canisters flying up to 2 miles away, resulting in the death of Turner Lee Salter, 19, who was struck by a nitrous oxide canister propelled by the blast.

Authorities received information on April 20 that Kestou was attempting to flee to Hong Kong, prompting his arrest. Macomb County Prosecutor Peter Lucido stated that Kestou, as the owner of the business, was considered a suspect from the beginning. Involuntary manslaughter is the highest charge currently being pursued based on the evidence available.

The cause of the fire has not yet been determined, but investigators believe it originated in the southwest corner of the building. Kestou has been released on a $500,000 bond, with the condition that he wears a GPS tether. A probable cause hearing is scheduled for May 7 in Clinton Township District Court. The Associated Press has reached out to Kestou’s attorney for comment.
