A former choirmaster accused of dozens of sexual assaults against 11 children has been charged with a further 15 offences against two more alleged victims.

Mark Burgess, of St Chads Avenue, Portsmouth, Hampshire, originally faced 58 counts, including buggery, indecent assault, gross indecency with a child, inciting sexual activity with a child, and sexual touching.

Hampshire Police have now announced the extra charges, taking the total to 73 offences.

A force spokesman said: "The offences relate to 13 children in total, who were under the age of 16, during Burgess' time as a choirmaster for the All Saints Church choir in Portsmouth and Westbourne Choir in Sussex between 1975 and 2009."

The 66-year-old has been bailed to appear at Portsmouth Magistrates' Court on July 23.
