Police in Northern Ireland are investigating a report that an indecent image appeared briefly during a children’s screening of the Super Mario Bros Movie.
The incident happened at Londonderry’s Waterside Theatre on Friday.
It is understood the children, believed to be of primary-school age, were at the event as part of a summer scheme.
It is believed an image of a partially undressed woman appeared on screen for several seconds before being removed.
The theatre has described what happened as “unfortunate but serious” and apologised.
