British counterterrorism police on Thursday raided the home and seized several electronic devices belonging to The Electronic Intifada’s associate editor Asa Winstanley.

Approximately 10 officers arrived at Winstanley’s North London home before 6 am and served the journalist with warrants and other papers authorizing them to search his house and vehicle for devices and documents.

A letter addressed to Winstanley from the “Counter Terrorism Command” of the Metropolitan Police Service indicates that the authorities are “aware of your profession” as a journalist but that “notwithstanding, police are investigating possible offenses” under sections 1 and 2 of the Terrorism Act (2006). These provisions set out the purported offense of “encouragement of terrorism.”

An officer conducting Thursday’s raid informed Winstanley that the investigation was connected with the journalist’s social media posts. Attempts to reach the Metropolitan Police Service for comment for this story have been unsuccessful.

Although his devices were seized, Winstanley was not arrested and has not been charged with any offense.
