JUST Yorkshire reported the incident, which took place at the Carlisle Business Centre, to police who are investigating.
Ms Shah said: “I didn’t hear it at the time because the heckling was so bad.

All confirmed candidates in Bradford West took part in the event.
Nadeem Murtuja, chair of JUST Yorkshire, which organised the hustings, said in a statement: “JUST Yorkshire condemns every form of hate, racism, Islamophobia and anti-Semitism.
