A dad has been jailed for five years after admitting killing his six month old son.

Plymouth dad Lee Anthony Sweet today pleaded guilty to killing Ruben Sweet-Harris.

The child also suffered nine “microfractures” to his ribs which showed his father had grabbed the baby under his arms and shaken him until he became unresponsive and floppy.

Sweet, of Park Avenue, Devonport, killed the infant in Plymouth on May 31 last year.
