The Police Service of Northern Ireland (PSNI) has "postponed" a scheme to make petrol station owners responsible for tracing drivers who do not pay, after a storm of criticism. Letters were sent to petrol stations in two districts Lisburn and Castlereagh, and Ards and North Down in July notifying them of the change, and saying it would come into effect at the start of August. Police said research showed up to 85% of drive-offs are "genuine mistakes" that do not require their input. However the scheme will now be reviewed.
