THE ICE CREAM WARS BBC2, 9pm

This compelling documentary tells the inside story of a vicious gang war in Glasgow’s tough housing estates in the early 80s, resulting in the murder of six innocent members of one family, including an 18-month-old baby. And the reason for the war? Ice cream van routes.

Among the city’s housing schemes, ice cream vans thrived, making so much money that they quickly attracted the attention of the city’s gangsters.

The violence became deadly on April 16, 1984, when a flat fire killed most of the Doyle family. One of the victims, Andrew Doyle, was a young ice-cream van driver. What followed was a court trial and a 20 year fight for justice.
