jamuna news desk: Samsung chief Lee Jae-yong has been questioned for a second time as a suspect in South Korea's biggest political corruption scandal.
Prosecutors are expected to decide based on the hearing whether they will seek an arrest warrant for Mr Lee.
The firm is accused of giving donations to non-profit foundations run by a confidante of President Park Geun-hye in exchange for political favours.
"I will once again tell the truth," Mr Lee told reporters before the hearing.
The Samsung chief had already been questioned with several other company executives in January but a subsequent court ruling decided there was insufficient grounds for an arrest.
Yet during the past weeks investigators reviewed the case and decided there were new aspects that required further questioning.
The claims against the company revolve around a merger between the electronics giant's construction arm, Samsung C&T, and an affiliate firm, Cheil Industries.
The prosecution alleges that Samsung gave 2.8m euros ($3.1m; £2.5m) to a company co-owned by Park confidante Choi Soon-sil and her daughter, in return for political support for the deal.
The scandal led to President Park being impeached last December.
