Morobe rural police commander Insp David Warap said police learned about this after they sent a team into the area to investigate why the principal was attacked.
Warap said 10 policemen that included five mobile squad members, four rapid response unit members and one detective were sent into Wasu last week after reports of the incident reached police.
Their trip was funded by the Kabwum district development authority.
“The attack (on the principal) was not related to his job,” Warap said.
“The angry male students attacked the principal because of his personal conduct.”
“He was reported to be going around with schoolgirls, which made the male students angry.”
Police last week said the new school vehicle which the principal was using and his home were damaged by the students.
The principal, from Enga, and his family escaped unhurt after they were rescued by Wasu police.
They were transported to Lae on a dinghy.
“Since arriving in Lae, I do not know where the principal is,” Warap said.
“He did not come to see police to lay any official complaint.”
Warap said police have moved into Wasu and took control of the situation.
He said police would be there for some time and travel to the interior Kabwum station and surrounding areas to attend to outstanding sorcery-related killing cases.
Provincial police commander Supt Augustine Wampe said this was the second incident involving the principal.
Wampe said the same principal was earlier held up by armed criminals at the Nadzab Airport in Lae, and escaped with K150,000 in cash belonging to the school.
Meanwhile, provincial education chairman Andrew Gena condemned the action of the principal, saying if the allegation against him was true then he ought to be suspended and investigated.
“Such behaviour is uncalled for from a senior education officer,” Gena said. I do not know how he is managing the school.
“I call on the SSO (senior standardsofficer) and the PPA (provincial programme adviser) education to send a team to Wasu to find out what happened.” The National / ONE PNG
