Uganda's largest telecommunications firm, MTN, has written to the country's industry regulator to protest against a raid by security agents on its data centre in the capital, Kampala, which ended in the disconnection of four of its servers, news agency Reuters reports.

The letter to the Uganda Communications Commission (UCC) said that during the 2 July incident, the security men, who identified themselves as members of the country's intelligence agency, also kidnapped one of its contractors who works for Huawei Technologies.

MTN said the security personnel forced the employee to grant them access to a data centre and then proceeded to forcefully disconnect four servers.

The South African-owned company said that the incident, "poses a serious security risk to our telecommunications infrastructure and customer data".

Godfrey Mutabazi, the head of UCC, confirmed to Reuters that he had seen the letter:

"Yes, yes I have seen on social media that letter. I don't know who leaked it but I received it, yes. They were complaining that they were raided," he is quoted as saying.

Police spokesman, Emirian Kayima told Reuters he was "aware of the letter but I am verifying at the moment. I can't comment for now."
