ZIMBABWEAN police were last week forced to wait for a fellow officer to either vomit or otherwise produce crucial incriminating evidence of bribery. Two officers stood guard last week over a fellow policeman they had just arrested for accepting two Z$100 bills, which he swallowed, and waited for him to release it by whatever means. The officers took him to a hospital where X-ray examinations showed the security wires printed into the bills in his belly. Determined to get the evidence for use as court exhibits, his colleagues did not give in but exercised patience. The policeman had solicited the bribe from a minibus driver, promising to destroy the driver’s outstanding traffic offence tickets.
