A 22-year-old man arrested after an explosion at a city centre restaurant is set to appear in court charged with preparing to commit acts of terrorism.
Nicky Reilly was arrested after undergoing hospital treatment following the blast at the Giraffe restaurant in Exeter on May 22.
He will appear before City of Westminster Magistrates' Court on Wednesday afternoon but the court could not confirm the time.
Reilly is charged under the Terrorism Act 2006 with "engaging in conduct in preparation for committing acts of terrorism".
He is also charged with possession of an explosive substance with intent, contrary to Section 3(1)(b) of the Explosive Substances Act 1883, and possession of explosives contrary to Section 4 of the same Act.
A Devon and Cornwall Police spokesman said: "Although one man has now been charged, this remains a complex, live investigation. We are therefore keen to speak with anyone who may have information about the man arrested at the scene of the explosion on May 22, Nicky Reilly, or others they believe may be involved in any capacity."
Two further men remain in custody, helping the police with their inquiries, the spokesman said.
Reilly, from Plymouth, is understood to have been the only person injured in the attack, suffering eye and facial injuries when the device partially went off in the shopping centre restaurant at lunchtime.
Following the blast, police officers carried out a number of searches at properties in Plymouth, including Reilly's flat and a Muslim community centre.
The two other men were arrested after the attack. One arrest took place at gunpoint in Plymouth city centre on Friday May 23 and the third man was arrested on May 28 at a residential property in the city.
