Police responded to the incident after the woman's call but did not issue any citations.
However, authorities questioned the family for one hour, according to Oakland Council member Lynette Gibson McElhaney.
McElhaney told the Huffington Post: 'In a city that needs significant policing services, we can't have those precious expensive resources squandered in a frivolous way.'
She added: 'Police are not a private security for any white person that's offended by the presence of black folks in our public spaces.'

'We will do our part to lean into the conversation thoughtfully and [make sure] that the activities of black people aren't being overly policed,' McElhaney said.
Also In April, two black men were arrested while waiting for a potential business partner in Starbucks while another man was denied bathroom use and had the police called on him.
In response, the franchise announced on Thursday it is changing its bathroom policy after the two videos went viral igniting a racial firestorm.
Another racial incident came last month when two Native American boys had the police called on them while touring CSU Fort Collins campus.
A white woman in the group called the police because she said they were acting 'quiet', wearing t-shirts with 'demons' on them and just did not belong.
