When can I be arrested?
A person may be arrested either on the strength of a warrant of arrest or when a police officer witnesses a person committing an offence or has probable cause to believe that a person was involved in the commission of a crime.
When approached by a police officer, one should remain calm. Do not flee or allow your first response to be an aggressive one. Offer your co-operation to the officer, do not resist arrest and never offer to pay a bribe. Should arrest be resisted, then reasonable force may be used by the officer to affect the arrest.
