It depends on the wording in your contract and the frequency of payment. If you are paid monthly in arrear and were sacked three weeks into the month, then yes you are "entitled" contractually if not morally, to pay.
You should check your contract for the terms in case of dismissal for gross misconduct which may preclude you receiving pay for notice and also accrued holiday pay.
If you actually do get this pay, I do hope your employer lays charges and pursues you for compensation, and the police do prosecute you. Doing what you have done puts other people's jobs at risk and why should a scumbag benefit from that?
