The charges and penalties for bribing a police officer can vary depending on the jurisdiction. However, based on the context provided, under the Bribery Act mentioned in the Law Reports, offering a bribe to a police officer can be considered a serious offense. 

For instance, Section 19 of the Bribery Act penalizes a public servant for accepting a gratification as a reward for performing an official act, which would include a police officer accepting a bribe. The specific penalties would be determined by the relevant sections of the law and the judicial system’s interpretation and application of those laws.

In the case of Sri Lanka, as per the context provided, the Bribery Act would be the governing legislation, and the penalties could include fines, imprisonment, or both. The severity of the penalty would likely depend on the nature of the bribe, the amount involved, the role of the police officer, and other relevant circumstances of the case. It is important to consult the specific provisions of the Bribery Act and related case law for precise penalties.
