A man has been arrested on suspicion of the attempted murder of a 17-year-old at a Traveller site near Desborough.

“A 41 year-old man was arrested on suspicion of attempted murder.
“The arrest was made in connection with the shooting of a 17-year-old boy at the Greenfield Traveller site, Braybrooke, on Sunday, July 10.
