A man has been charged with stabbing to death three men in a Reading park.
Khairi Saadallah, 25, has been charged with three counts of murder and three counts of attempted murder, Thames Valley Police said.
Friends James Furlong, 36, David Wails, 49, and Joe Ritchie-Bennett, 39, all died in the attack in Forbury Gardens on 20 June. It was later declared a terrorist incident.
Mr Saadallah, who is from Reading, will appear before magistrates on Monday.
Three other people hurt in the attack have since left hospital.
Counter Terrorism Policing South East continues to lead the investigation.
Mr Furlong was head of history and government and politics at The Holt School in Wokingham. His parents said their son was “beautiful, intelligent, honest and fun” and “will live in our hearts forever”.
Mr Ritchie-Bennett was a US citizen who moved to the UK 15 years ago. His father Robert Ritchie told US TV network CBS the family was “heartbroken” and said his son, who was originally from Philadelphia, was “brilliant and loving”.
And scientist Mr Wails was described as “always happy” and a person who “always made people smile”.
Members of the victims’ families were expected to attend a private vigil in Reading on Saturday evening. Reading Borough Council is streaming the vigil online.
People taking part in the virtual memorial have been encouraged to light a candle and place it on their doorsteps or in their windows, while local officials are giving speeches.
Council leader Jason Brock said: “There is an overwhelming sense of grief within the Reading community about last Saturday’s tragic events.
“The council and public are united in their desire to mourn the victims and appropriately remember them.”
Thames Valley Police Chief Constable John Campbell said: “In times of such tragedy, we often see the best of our communities and that has certainly been the case in Reading.
“I know it will take time for everyone to heal but we stand alongside you and will do all that we can to support you, as your police.”
