An 11-year employee of American Airlines was arrested Monday on suspicion of stealing a passenger's laptop.
"It was one that had been traced to a location based on its Internet usage," DFW Airport spokesman David Magana said. "Denver police asked our officers to follow up."
Officers observed "numerous items that are commonly stolen from passengers' luggage and from planes" inside Masumoto's house, according to detectives' notes.
Masumoto has only been charged with one count of theft so far.
"The only thing that this case involves right now is the laptop," Magana said.
Masumoto is the second AA employee in less than a month to be arrested on suspicion of stealing from passengers at DFW Airport.
"The overwhelming majority of American's 24,000 employees in North Texas are honest and hard-working," American Airlines spokeswoman Andrea Huguely said in a statement. "American has no tolerance for behavior such as this."
Masumoto is out on bond. The airline fired Masumoto, who worked in the maintenance department for 11 years.
