It is said that Tuyishime was especially targeting individuals with cases or whose relatives are battling legal actions for their alleged unlawful acts.
Chief Inspector of Police (CIP) Hamdun Twizeyimana, the Police spokesperson for the Eastern region, said that Tuyishime was arrested after defrauding a local resident of Rwf50,000.
"The suspect learnt that a local elderly woman had a son, who was arrested recently over assault causing body injuries," CIP Twizeyimana said.
Tuyishime is also a local resident in Muzizi village, Rukara Cell in Rukara Sector.
"He approached the family calling himself a member of law enforcement organs with powers and demanded Rwf200,000 to release their detained relative.
They bargained and settled for Rwf50,000 for the service. The woman paid the money, waited for the release of his son in vain, which prompted her to bring the matter forward to Rukara Police station," CIP Twizeyimana said.
Tuyishime was located and arrested.
According to CIP Twizeyimana, it is not the first time that Tuyishime has been implicated in similar criminal activities.
"He was equally wanted in connection with defrauding other disadvantaged families in Kawangire and Rukara cells, recently, promising to get them financial support offered under Vision Umurenge Programme."
The spokesperson advised the public to avoid taking shortcuts, which are also unlawful in nature and make them prey to such fraudsters.
"Go through the right channels to get a service you need rather than rendering yourself vulnerable to criminal attempts."
Clause One of article 174 of the law determining offences and penalties in general, defines fraud as deception, obtaining another person’s property, whole or part of his/her finance by use of false names or qualifications, or offering positive promises or threats of future misfortunes.
Clause Two of the same article provides a term of imprisonment of between two and three years, and a fine of not less than Rwf3 million but not more than Rwf5 million, upon conviction.
