(a) an offence or a breach of the peace is being or is likely to be committed, or a person has suffered physical injury or there is imminent danger of injury to a person or damage to property; and
(b) it is necessary to enter the premises immediately for the purpose of preventing the commission or repetition of an offence or a breach of the peace or to protect life or property.
