Transport Operational Command Unit (TOCU) officers carried out spot checks on The Strand and Westminster, in central London, on Friday night.

Officers also targeted drivers illegally touting for business outside pubs and clubs in the area.

During the operation 187 vehicles were stopped, 44 removed, there were 18 arrests and 23 drivers reported for summons and 27 fixed penalty tickets issued.

Chief Inspector Chris Rose, from the TOCU, said: "We will not tolerate illegal minicabs in London and Friday's operation highlights our continued commitment to keeping London safe.

'Dangers of illegal minicabs'

"Unlicensed minicabs can often be potential death traps and passengers need to be safeguarded.

"You should never underestimate the dangers of illegal minicabs especially to your own personal safety, especially to lone women."

Twenty-nine minicab offices were also visited to ensure they had registered drivers and three were found to be operating illegally.

Bailiffs from Westminster City Council removed vehicles which had outstanding fines.
