Five people were reported for a possible £10,000 fine while 217 others were issued fixed penalty notices for organising large gatherings.
London is currently in tier 4 meaning households cannot mix
indoors, although an individual can meet one other person in an open public space.
Officers were called to a total of 58 illegal large gatherings
as people celebrated the start of the new year.
Police said four people had been arrested in the capital for
breaching Covid regulations.
