Sanjay Singh alleged that outsiders were called to trigger violence in Delhi.
Accusing both the BJP leaders and Delhi police personnel being behind the last week's violence in the capital's North East district, the AAP on Sunday demanded probe into the violence by a joint parliamentary panel as well a sitting high court judge.
Speaking to the reporters in Lucknow, AAP's national spokesperson and Rajya Sabha MP Sanjay Singh went on to demand narco tests as well of the BJP leaders and police officials.
"The violence which took place in Delhi was the result of a well-planned conspiracy of the BJP. The BJP leaders and police officials involved in this should undergo Narco test," said Mr Singh.
"The test should be telecast live on television so that the entire country can know the truth," he asserted.
Demanding establishment of a Joint Parliamentary Committee to probe the recent violence in North east Delhi, Mr Singh said, "A judicial probe by a sitting high court judge too should be held."
He also alleged that outsiders were called to trigger violence in Delhi.
"This makes it amply clear that the riots took place at the behest of the BJP," said Mr Singh.
