VIDEO: Mayor caught throwing dog mess on path of opponent's house

The mayor of a wealthy California town who was caught on camera tossing dog dirt onto the walkway of a political opponent is being asked to resign by residents.

During a City Council meeting, San Marino residents criticised mayor Dennis Kneier and called for him to step down, despite his subsequent apology.

Police cited him for littering, which can carry a fine of up to $1,000.

The mayor of the tidy Los Angeles suburb says he found a bag of dog dirt on a parkway on Saturday and tossed it onto the front path of a home.

The homeowner, Philip Lao, is a political opponent.

He recognised the mayor on surveillance video and called police.
