Another American doctor is suspected of taking part in another illegal lion hunt near the same park where "Cecil" was killed.
According to Zimbabwean officials 68-year-old Jan Casmir Seski of Pittsburgh is a suspect in an illegal crossbow hunt that took place in April.
Officials say the owner of the company that conducted Seski's hunt has been arrested.
Seski is the second American implicated in an illegal lion hunt in the past few months.
In July, Minnesota dentist Walter Palmer created an international outcry when it was discovered he killed a lion named Cecil at the park.
He has gone into hiding the past week and is facing extradition back to the African country to face charges.
Palmer said he relied on his local guides to ensure his hunt was legal.
