A man has confronted and detained a gunman who tried to rob his parents at their newsagents in Liverpool.
The man burst into the Tom Draper store in Town Row, West Derby, just before 1400 GMT and threatened the couple, who are both in their 70s.
Their 42-year-old son challenged the man, took hold of the gun and kept hold of him until police arrived.
A 33-year-old man from the West Derby area has been arrested on suspicion of attempted armed robbery, police said.
Ch Supt Jon Ward, of Merseyside Police, said: "The owners of Tom Draper newsagents were extremely brave to have challenged and detained this man and I would like to thank them for their courage in the way they have responded today.
"It sends a strong message to criminals that the community is not prepared to tolerate such acts of violence and criminality.
"However, we would never encourage members of the community to put themselves at risk by confronting offenders and urge any victims of an ongoing crime to keep themselves safe and call 999. Possessions can be replaced - human lives cannot."
