Jakarta – A student attacked a university lecturer in East Timor for trying to teach dispite a student boycott, a report here said Saturday.

Students at Universitas Timor Timor, in Dili, have called for a boycott to demand the release of students arrested during violence there last week.

Trisno Sumbodo, a lecturer in the agrigulture department, was kicked in the stomach three times by one of his students when he tried to teach on Tuesday, the Kompas daily said.

The students have called on lecturers to halt courses until six students who were detained by police on November 14 are released, the daily said.

East Timor Police Chief Colonel Atok Rismanto said on Wednesday the six students will be charged with violence against security officials following a clash between students and Indonesian security forces at the university.

Clashes erupted after pokice and soldiers entered the campus following an earlier brawl between plainclothes security forces and students. At least seven people were injured and 13 were arrested.

The agriculture department has since remained closed.

The university suspended courses there shortly after the initial clash in an effort to prevent further unrest.

The management of the university Friday met with the police chief in Dili to discuss the incident, the daily said without giving further details.

Police chief Rismanto could not be immediately reached for comment.

Universitas Timor Timor is a hotbed of East Timorese pro-independence student activists.

Indonesian troops invaded East Timor in 1975 and Jakarta unilaterally declared the former Portuguese colony its 27th province the following year.

The United Nations and most states still recognize Lisbon as the official administrator of the territory.
