The teenager contacted police who arrested a 55-year-old woman at Guildford train station. Lindsay Li (left) and the woman who has been arrested after a tirade on a Sydney bus. She was taken to Merrylands police station where she was charged with six counts of common assault and two counts of using offensive language. The arrest comes after 29-year-old Lindsay Li was subjected to a slew of racial insults as she caught her usual bus 273 home for lunch from Willoughby to Crows Nest in Sydney's north. When the woman reeled around on the bus and allegedly began throwing racist insults at Ms Li, the younger woman pulled out her phone and began filming.

The video footage apparently shows an older woman with blonde hair allegedly unleashing a tirade of racial slurs, calling Ms Li a "f---ing ugly f---ing chink" and accusing her of selling drugs. Fairfax Media has since received several reports from passengers on Sydney public transport and pedestrians in the city who say they have been on the receiving end of racial verbal abuse from the same woman. A second video seen by Fairfax Media shows a woman bearing a striking resemblance to the woman in Ms Li's video hurling abuse at several passengers on a train at Central station last Thursday. The incident was reported to police by Sydney Trains staff. Several other reports detail separate incidents in which commuters and pedestrians were left in tears after being on the receiving end of angry outbursts from a woman resembling the individual in Ms Li's video. One person claimed the woman racially abused a female student on a school excursion, calling her a "suicide bomber", leaving the student extremely upset.

Police have also received multiple complaints about the woman. According to police about 12.35pm on September 7 a woman and her son were on the platform at Edgecliff train station, when they were approached by a woman who allegedly verbally abused and spat on them. The following Monday a woman was at the Bondi Junction interchange when she was approached by a woman who allegedly spat and verbally abused her. The woman allegedly spat again, hitting another passenger. Last Friday, a man was walking on a pedestrian footbridge on Florence Street, Hornsby, when a woman approached him and allegedly spat in his face. Meanwhile, the bus driver accused of doing nothing when Ms Li was subjected to a barrage of racial abuse was found to have followed the correct protocols in response to the incident.

Ms Li said the bus driver ignored her pleas to stop the bus and call the police. But State Transit has reviewed the bus CCTV footage of the incident and found the driver took all necessary actions in response to the incident. "This included making a call to State Transit's Network Control Centre to request assistance, about one minute after being notified by the customer, and as soon as it was safe to do so," a spokeswoman for State Transit said in a statement. "We will continue to work with NSW Police on this matter and provide assistance where required," the statement read. It is understood bus drivers are directed not to engage with passengers who exhibit antisocial behaviour, but to contact the control centre via the bus radio. The control centre can then contact emergency services if appropriate.

On Thursday night, officers from Police Transport Command were out in force targeting anti-social behaviour on public transport in and around Sydney. Operation Disrupt involved 65 police officers deployed across the CBD, Sydney"s north and south-west patrolling 100 trains, 98 train stations and 25 buses. During the operation, Police Transport Officers issued more than 100 infringement notices for a range of transport offences, 74 people were moved on for antisocial behaviour, 19 people were searched, and eight people were arrested. "The Police Transport Command will continue to target antisocial behaviour and fare avoidance on public transport tonight and throughout the summer," Superintendent Joyce said.
