Two brothers from Manchester have been hailed as heroes after they helped tackle a man who allegedly stabbed a woman in the Australian city of Sydney.
Luke and Paul O'Shaughnessy said they heard a commotion and looked out the window to see a man standing on the roof of a car wielding a knife.
They ran down from their fourth-floor office, chased the attacker and, with the help of others, tackled him to the ground and pinned him down with a chair and milk crate.
The group of responders is also said to have included fellow Manchester man Lee Cuthbert.
Police said the suspect - a 21-year-old man from Maryong in New South Wales - attempted to stab several people before being arrested.

They confirmed they were investigating allegations the suspect yelled "Allahu akbar", or "God is great", but are not treating it as a terror incident.
A woman was found dead in a building nearby and police were investigating if the earlier stabbing at a hotel on the corner of Clarence and King streets was linked to the street attacks.
Australian prime minister Scott Morrison commended the “brave” bystanders for intervening, while New South Wales Police Superintendent Gavin Wood said: “These people are heroes, and I want to acknowledge that”.
Both Paul and Luke said they were "proud" of their actions, but denied they were heroes.
Paul said: "I didn't even think about it – I just thought is my brother going to be OK as we ran towards him."
Brother Luke added: "I just wanted to make sure he couldn't hurt anyone else and if it happened again I would do it again and act quicker."
