BOSTON (Reuters) - A Massachusetts man arrested late Tuesday as part of a terrorism investigation will face charges in federal court on Wednesday, the day after another suspect in the probe was shot dead, according to prosecutors.
Police arrested the man, named as David Wright by a spokeswoman for U.S. Attorney for Massachusetts Carmen Ortiz, in Everett, outside Boston. He is due to face charges at 3:30 p.m., officials said.
Officers working with the Joint Terrorism Task Force had earlier shot and killed Usaamah Abdullah Rahim, who had been under 24-hour surveillance, after police contend he confronted them with a knife.
The pair had planned to try to behead a police officer on Tuesday, the Boston Globe reported on Wednesday, citing a law enforcement official who was briefed on the case. The report could not immediately be confirmed.
Police have offered little detail on why Rahim was being watched or what charges Wright would face when he appears in court.
Boston Police Commissioner William Evans on Tuesday told reporters only that they considered Rahim "a threat" and that investigators had found information about him that raised a "level of alarm."
Evans said police had approached Rahim in a parking lot to ask him questions and that he responded by drawing a knife and threatening them.
Local prosecutors have opened an investigation into whether the police shooting was justified.
The apparently foiled attack came six months after a pair of New York City police officers were shot dead while sitting in their patrol car in an attack intended as retribution for recent police killings of unarmed black men.
