presence, under penalty of fine and imprisonment. By the Prevention of
Offences Act 1851, a private person is allowed to arrest any one whom he
finds committing an indictable offence by night, and under the Malicious
Damage Act 1861, any person committing an offence against that act may
be arrested without warrant by the owner of the property damaged, or his
servants, or persons authorized by him. So, too, by the Coinage Offences
Act 1861. s. 31, any person may arrest any one whom he shall find
committing any offence relating to the coin, or other offence against
that act.
A person arrested without warrant must not be detained in private
custody but must be taken with all convenient speed to a police station
or justice and there charged (Summary Jurisdiction Act 1879).
