The first victim of the London Bridge terror attack to be named has been praised by his father as "a beautiful spirit".
Jack Merritt, 25, was one of two people stabbed to death by Usman Khan during the convicted terrorist's rampage on Friday.
Khan, 28, was shot dead on the bridge while wearing a fake explosives vest by police.
Merritt, a course coordinator at Cambridge University's criminology institute, was killed as he helped host an event near London Bridge to mark five years of a prisoner rehabilitation programme.
It was targeted by Khan, a former participant, who arrived armed with two knives.
"I am sad beyond words to report that a course coordinator, Jack Merritt, was killed," Stephen Toope, Cambridge University vice-chancellor, said in a statement.
"Our University condemns this abhorrent and senseless act of terror."
David Merritt has criticised that response, writing in one social media message: "We don't need knee-jerk reactions."
In another post subsequently deleted, he said his son "would not wish his death to be used as the pretext for more draconian sentences or for detaining people unnecessarily."
