A woman has been charged by police after she failed to complete a breathalyser test following a crash.

Sidcup Police took to Twitter on Sunday to share the news.

"Traffic officers attended an RTC involving 2 yesterday on Station Rd," the tweet read.

"A female was arrested for failing to complete the breathalyser when requested."

The 49-year-old from Sherwood Park Avenue has since been charged with failing to cooperate with a preliminary test and failing to provide in custody.
