A man who allegedly attempted to burglarize a Fremont apartment building that was being fumigated with a hazardous chemical Wednesday later died at the hospital, according to police.
Police and firefighters were dispatched to the 39800 block of Fremont Boulevard at 2:22 p.m. on a report of a man on the ground with difficulty breathing.
The man was initially detained in a patrol vehicle, but police said he was compliant and no force was used in the arrest.
Paramedics with the Fremont Fire department evaluated the man and transported him to a hospital, where he was pronounced dead.
Investigators later determined that he had allegedly spent several minutes in part of the apartment complex covered by a fumigation tent marked with "Do Not Enter" signs announcing the presence of the chemicals sulfuryl fluoride and chloropicrin.
After leaving the tent, he suffered a medical emergency and later died, according to police. The man's name is not yet being released.
Along with Fremont police, the in-custody death is also being investigated by the Alameda County District Attorney's Office.
