A constable may enter and search a place without a warrant if he or she has reasonable grounds—
(a) to suspect that an offence punishable by imprisonment for a term of 14 years or more has been committed, or is being committed, or is about to be committed; and
(b) to believe—
(i) that evidential material relating to the offence is in that place; and
(ii) that, if entry is delayed in order to obtain a search warrant, the evidential material will be destroyed, concealed, altered, or damaged.
