Police alerted two years ago over Essex teacher who had indecent images – The Guardian
‘Police have been accused of a series of failings that left a deputy headmaster free for two years to secretly film pupils undressing using cameras hidden in an Essex school’s changing rooms. Scores of indecent images of boys aged nine to 12 were found at the home of Martin Goldberg, 46, a maths teacher at Thorpe Hall school in Southend, who took his own life this month after being visited by detectives.’
