Polytechnic University President Urges Hong Kong Protesters to Leave William Gallo HONG KONG - The president of the Polytechnic University under siege in Hong Kong, has said he has brokered a truce with police. Teng Jin-Guang said it would allow the hundreds of protesters trapped inside the campus to leave peacefully. Teng said he received assurances from police for a temporary suspension of the use of force if the protesters do not initiate the use of force. "We have also received permission from the police for you to leave the campus peacefully, and I will personally accompany you to the police station to ensure that your case will be fairly processed," Teng said. It is unclear whether and when the truce was taking effect. Waves of students fled on foot late Monday, running through clouds of tear gas as they attempted to break through police lines. It was the second concerted attempt by students to flee the urban campus, which has been surrounded by police who have repeatedly warned they will use lethal force. Live feeds showed riot police chasing down students, some of whom were covered in blood. It wasn't immediately clear how many were arrested and how many may have escaped the campus successfully. The clashes raised fears that the siege would end in a deadly crackdown. .
