He calls himself the Apostrophiser. He patrols and silently corrects punctuation mistakes made on hoardings in public areas across the city of Bristol. He made these corrections under cover with only his family and close relatives made aware of his self proclaimed vigilantism.
The Apostropher is a qualified engineer and does not want to reveal his identity – saying that his work is to save the youth from learning wrong grammar.
He takes pains to correct the mistakes using the same font and colour of the original hoardings.
At Tux & Tails in Gloucester Road he corrected 'gentleman' to 'gentleman's' and Jason Singh the manager told The Times that "I'm not going to lose any sleep over it. He could have let me know before doing it."
The police said that he was not breaking any laws by causing any permanent damage to the properties of shopkeepers and his vigilantism has been welcome by many in the city.
