An American citizen was kidnapped from his residence in Model Town Lahore on Saturday, police said.
Police identified the man as “J.E. Warner”, who they said was working on a development project tribal areas.
A U.S. Embassy spokesman said they were trying to confirm the reports.
“Some six to eight people broke into his house at around 3:30 a.m.” police official Tajamal Hussain told Reuters.
“Two of the assailants came from the front gate while about six others used the backdoor. They tortured the guards and then took the American with them.”
Hussain said Warner, in his 60s, had been living in Pakistan for five to six years. He mostly lived in Islamabad but had been travelling to Lahore.
Another official said they had no details about the kidnappers.
Pakistani Taliban, linked to al Qaeda, had claimed responsibility for kidnapping a Swiss couple in July.
They said the couple could be freed in exchange for Dr. Afia Siddique who is imprisoned in United States for allegedly attacking soldiers in Afghanistan.
