Lamu West Member of Parliament Stanley Muthama was on Monday presented in court to answer to charges of tax evasion.
The MP denied the charge on Sh487 million tax fraud by a company he owns and was released on a cash bail of Sh500,000.
The legislator was arrested on Thursday night at the Jomo Kenyatta International Airport (JKIA) after being trailed by DCI officers.
Muthama appeared at an Eldoret Court and a mention of the case was scheduled for a later date.
