(CNN) -- The United Arab Emirates on Saturday expressed concern about a German court's decision to release an alleged Israeli agent being investigated in connection with a Hamas leader's murder in Dubai. The suspected agent, who often uses the alias Uri Brodsky, is under investigation for helping obtain a false German passport allegedly used by one of the killers in January. The UAE's foreign ministry said it's worried about Brodsky's release on bail and his freedom to return to Israel during the probe, the state-run WAM reported. Brodsky still faces a possible trial in Germany "The UAE seeks assurances that Brodsky is in no way connected with the murder of Mahmoud al-Mabhouh in Dubai in January of this year," ministry official Abdurahim Al Awadhi said in a statement.
