The mother of a Ghanaian teenager shot dead in New York is travelling to the United States to plan her son's funeral after President Donald Trump agreed to grant her a visa.

Maame Gyamfi was escorted to the airport by relatives and Dr Erieka Bennett, Head of Mission of the African Diaspora Forum.

"I'm going to America to plan my son's funeral," Gyamfi said.

She thanked the government and well-wishers for their support and prayers following her son's death.

New York Mayor Zohran Mamdani announced on Saturday that Trump had agreed to grant Gyamfi a visa so she could mourn her son in person.

"Javits Frimpong's mother deserves to say goodbye to her son in person. I just got off the phone with President Trump, and he has agreed to grant her visa immediately," Mamdani said.

He described the murder of a child as a pain no parent should endure, "let alone from thousands of miles away," and added: "All of New York City is mourning this tragedy."

Ghana's government has condemned the killing and said it is following the case closely to ensure justice. It has urged US authorities to conduct a thorough investigation and stated it is ready to provide legal and consular support to bring the perpetrators to justice.

Police are searching for three teenage suspects who fled the scene and were captured on surveillance footage.

The shooting has sparked concern among Ghanaians about the safety of children sent to study in the United States.
