NEW YORK, Aug. 1 (UPI) -- A 32-year-old man was arrested in Saturday's bomb scare that emptied New York's LaGuardia Airport's main terminal, a Port Authority spokesman said.
Port Authority spokesman John Kelly told CNN that Scott McGann of New york is accused of bringing a bag containing wires and a battery into LaGuardia, prompting the evacuation and temporary closure of the airport's central terminal.
Authorities charged McGann with making terrorist threats, placing a false bomb or hazardous substance in the first degree, and placing a false bomb or hazardous substance in a transportation facility.
Meris Campbell, a Queens district attorney's office spokeswoman, said if McGann is convicted on the three charges, he could face up to seven years in prison. No motive was given for McGann's alleged actions.
An unidentified law enforcement source told CNN McGann allegedly came to the airport with a backpack containing two six-volt square batteries with attached wires, along with several personal items and unspecified electronic devices.
The source said McCann was arrested twice in 2008 and was accused of tampering with evidence and resisting arrest in June.
Kelly said LaGuardia Airport's central terminal was evacuated at 5:20 a.m local time and reopened at midmorning. An unspecified number of passengers were forced to wait outside the terminal in the wake of the bomb scare.
