The 35-year-old businesswoman was the only female candidate that has shown interest in the presidential elections held in August.

She, however, failed to fulfill all the requirements for being nominated as candidate by Rwanda’s National Electoral Commission(NEC), though, as she fell short of the required number of signatures in all districts in the country, according to NEC.

"She is being accused of alleged forgery and tax evasion which prompted police to conduct a search at her home on Tuesday," said Theos Badege, police spokesperson.

The search was part of preliminary investigations into alleged crimes, her family’s lawyers are cooperating with the police on the case, Badege told Xinhua in a phone interview.

The police said investigations are ongoing before the case can be opened to the public.

Badege also termed reports saying her and some of her family members have been arrested by the police as "fabricated lies and misleading information."

"Rwigara and her family are safe.

"The police did not arrest any of Rwigara’s family." he added.

Rwandan media The New Times in July reported the opposition party Social Party Imberakuri (PS-Imberakuri) said Rwigara illegally accessed confidential party documents including the list of its members and used it to accumulate the required number of signatures for her nomination papers.

About 6.9 million Rwandans cast ballots in the presidential election held on August 4.
