"Halfway through the meeting a group of unruly youngsters disrupted the gathering," De Lille said in a statement.
"Despite our best efforts to address the community, we had to call it off in the interest of the safety of over a 1000 members of the community who were attending the meeting," De Lille said.
She said the meeting was an example of how the provincial ANCYL were making the city ungovernable and impeding the rights of ordinary citizens.
Western Cape ANCYL spokeswoman Nyameka Mguzulo denied the League was responsible for disrupting the meeting and said poor service delivery in the township was to blame.
"We're not surprised," Mguzulo said. "She's always blaming the ANCYL and not looking at the real issues affecting people in the community."
Mguzulo accused De Lille of neglecting service delivery in some areas of Khayelitsha.
"That is exactly why people were angry. They're angry because there's no service delivery in the areas where they are," Mguzolo said.
De Lille was attending the meeting to lead a delegation from the mayoral committeey who would report back to the community on how their input had affected the city's development plans.
Their report would have also included information on the city's service delivery projects for Khayelitsha.
Mguzulo argued that De Lille's plans would neglect much of the Khayelitsha community.
"Many people were left behind because there's this agenda she's trying to push," Mguzulo said.
De Lille said the community meeting would be rescheduled in Khayelitsha.
"We will not be deterred by the illegal actions of a small politically motivated minority," she said.
