On April 21, 2025, the United Nations Office on Drugs and Crime (UNODC) released a new report on a global expansion of East and Southeast Asian organized crime groups.

On April 10, 2025, in an unsigned order, the U.S. Supreme Court unanimously ordered the government to try to return a Salvadoran national and U.S. permanent resident, Abrego Garcia, whom it had wrongly deported to a terrorist prison in El Salvador. However, the Court also observed that the courts may not have the authority to require the executive branch to return him. After the order, U.S. District Judge Paula Xinis attempted to force the administration to communicate its efforts, or lack thereof, to facilitate Abrego Garcia’s release. Instead, the administration made an emergency appeal and request for a stay, which the Court of Appeals for the Fourth Circuit quickly and unanimously rejected.[1]

Late last month, Irish and Spanish authorities thwarted the efforts of one of Ireland’s most notorious and high-level criminal networks, “The Family,” based in West Dublin.

Authorities arrested twelve suspects, between the ages of thirty and sixty, who are alleged to have participated in a drug-trafficking operation that involved transporting drugs between Ireland and Spain. Irish authorities originally arrested five men on Monday, March 24, and later detained the sixth man in Dublin. The other six suspects were arrested in Spain. 

On April 7, 2025, Justice Roberts, in a per curiam opinion, ruled that the Trump administration could appeal and then vacated the Temporary Restraining Orders issued by Judge Boasberg.

In April 2025, the United States and Russia conducted their second high-profile prisoner swap since the beginning of President Donald Trump’s current term, exchanging Russian American ballerina Ksenia Karelina for dual German Russian national Arthur Petrov. Karelina, who had been sentenced to 12 years in a Russian penal colony for making a $50 donation to a U.S.-based charity supporting Ukraine, was designated by the U.S. government as wrongfully detained in October 2024.[1] Petrov, meanwhile, was accused of conspiring to smuggle sensitive U.S. microelectronics to Russia’s military industrial sector in violation of export controls imposed after Russia’s 2022 invasion of Ukraine.[2]

On April 14, 2025, the U.S. Department of Justice (DOJ) announced the transfer of 13 Mexican nationals serving prison sentences for drug distribution-related convictions in the U.S. to Mexico.[1] On April 9, the U.S. Immigration and Customs Enforcement removed Tomas Jesus Yarrington Ruvalcaba, 68, a citizen of Mexico and former governor of the state of Tamaulipas, who was wanted by Mexican authorities.[2]

On April 9, 2025, the District of Utah unsealed a criminal complaint charging four US citizens with conspiring to conduct an illegal coup d’état against the Democratic Republic of the Congo (DRC). Of the four men — Marcel Malanga, 22, Tyler Thompson, 22, Benjamin Zalman-Polun, 37, and Joseph Peter Moesser, 67 — only Peter Moesser was arrested on US soil.[1] The three other men (Marcel Malanga, Tyler Thompson, and Benjamin Zalman-Polun) have already been tried and convicted in the DRC.  They are currently being held in New York and are expected to make their initial appearance soon at a federal courthouse in Brooklyn. Moesser made his initial appearance at federal court on April 10, 2025, in Salt Lake City, Utah.
