This is how he repaid the infidels:

A second suspect was arrested on Saturday in connection with the subway attack at London’s Parsons Green station that left 30 people injured, officials announced on Sunday as the city’s terror threat level is downgraded to “severe.”

A 21-year-old man was arrested late Saturday night in Hounslow in west London under the Terrorism Act, authorities said. Another 18-year-old man was arrested earlier in the day at the port of Dover, where ferries leave for France, and is also being held under the Terrorism Act. The suspects’ names have not been released and no charges have been filed.

Little details are known about the suspects and whether they are suspected of planting or building the bomb. The 18-year-old, whom authorities tracked using facial recognition technology, was believed to be a foster child taken in by Ronald Jones, 88, and his wife, Penelope, 71, who were honored by Queen Elizabeth for taking care of 268 foster children, the Times of London reported.
