NEW YORK (1010 WINS) -- An MTA control tower in Queens was forced to shut down once again for fumigation after bed bugs were found on Monday night.
According to Metropolitan Transportation Authority spokesman Tim Minton "one bug" was discovered at the Continental Master Control Tower in Forest Hills.
For the second time in a week, exterminators were brought in to fumigate the tower after the evening rush.
Last week, the tower was shut down during rush hour to be fumigated, causing major delays for thousands of riders.
Officials said they were unsure of where the bugs were coming from.
"It is conceivable that this bug originated somewhere other than these premises," said Minton. "We cannot conclude and we do not conclude that the source was internal."
On Jan. 8, an employee reported spotting bedbugs near some chairs and that area was fumigated.
A rep said that the four chairs that employees had been worried caused the infestation were removed and will be replaced.
