Police have ordered former vice president and leader of the newly formed opposition coalition Dr Mohamed Jameel Ahmed to come in for questioning over the forged warrant to arrest the president within 14 days.
In addition to Jameel, police are also looking to question opposition aligned Raajje TV Chairman over the investigation.
Jameel and Akram are both currently living in exile in the United Kingdom.
Police in a statement vowed to pursue legal action if the pair fail to obey the order.
Jameel had fled to the UK last July days before he was impeached in a controversial vote which was alleged to have been orchestrated by his eventual successor Ahmed Adheeb Abdul Ghafoor who himself was impeached following a blast aboard the presidential speedboat.
He has now been convicted and sentenced to prison for orchestrating the blast, now confirmed as a plot to kill the president.
The newly formed opposition alliance had said it will seek to oust incumbent president Abdulla Yameen Abdul Gayoom and form an interim government to ensure free and fair elections scheduled in 2018.
Five rival opposition groups had announced a united front to remove president Yameen from office.
The Maldives United Opposition brings together the Maldivian Democratic Party, the Adhaalath Party, two of Yameen’s former deputies and his former defence minister.
Meanwhile, the former chief prosecutor Muhuthaz Muhsin was convicted of terrorism and sentenced to 17 years in prison after the court found him guilty of forging the warrant to arrest the president.
The arrest warrant was issued from the Alif Dhaal Maamigili magistrate court in February. In addition to Muhuthaz, the chief magistrate of the court Ahmed Nihan was also sentenced to prison over the case.
A prosecution witness had testified that the warrant was sought on orders of the ex VP Jameel, an accusation he strongly denies.
