Two siblings, Alen Zheng and Ann Mary Zheng, have been charged in connection with an improvised explosive device (IED) found at MacDill Air Force Base in Tampa, Florida. According to multiple reports, Alen Zheng allegedly planted the bomb on March 10 and fled to China, while his sister was arrested for aiding him.

Alen Zheng faces three counts: attempted damage of government property by fire or explosion, unlawfully making a destructive device, and possessing an unregistered destructive device. His sister Ann Mary Zheng has been charged with one count each of evidence tampering and accessory after the fact for helping her brother flee and destroy evidence.

The bomb was discovered on March 16 in the base's visitor center, four days after it was planted. Investigators found residue matching the explosive in a vehicle used by the Zhengs, which they sold before fleeing to China. The device did not detonate but could have been potentially deadly, according to U.S. Attorney Gregory Kehoe.

MacDill Air Force Base is home to several critical commands, including U.S. Central Command and U.S. Special Operations Command. The base plays a crucial role in ongoing operations in the Middle East and elsewhere. The FBI is investigating the case, although there is no official extradition treaty with China.

Ann Mary Zheng was arrested upon her return to the United States on March 17, while Alen Zheng remains at large in China. Investigators tied Alen Zheng to the phone used to place a 911 call reporting the bomb and found components consistent with the device at his home.
