Malawi threatened on Thursday to arrest protesting villagers blocking construction of Madonna’s multi-million dollar girls academy, a new controversy for the singer in the African country where she has adopted two children.

About 140 villagers are demanding more money for land the government has leased to Madonna’s charity – Raising Malawi – for 99 years.

District Commissioner for Lilongwe Charles Kalemba, other senior government officials and Raising Malawi failed to reach an agreement in talks with representatives of the villagers on Thursday in a bid to resolve the dispute.

“If we cannot agree on this and if you cannot understand that this is government land, then I will have no choice but tell police to arrest you people for blocking development work on the site,” Kalemba told the village chief, Chinkhota.

Madonna launched the construction of the school last month and pledged to build similar facilities in other countries if the project succeeds.

The Raising Malawi Academy for Girls — in Chinkhota village about 15 km (10 miles) outside the capital Lilongwe — is expected to be completed in two years and will admit 500 girls from the small southern African country’s 28 districts. The construction is expected to cost $15 million.
