Men suspected of brutal attack on Hong Kong businessman ‘fled to Pakistan’
Police source says pair who allegedly stabbed a Pakistani businessman in Tsim Sha Tsui last year have fled to their hometown via Shenzhen

Police believe suspects in a brutal attack on a Pakistani businessman in Tsim Sha Tsui more than a year ago have fled to Pakistan, with which Hong Kong has no extradition treaty.
A tip-off was received that the suspects - Ali Bilal, 28, and Muhammad Imran, 33 - were hiding in Punjab province, a police source close to the case said.
The force has asked the Department of Justice to request that Pakistani authorities enforce an Interpol "red notice", issued in January to locate and arrest them, the source said.
A red notice from the international police agency is akin to a global arrest warrant.
"Police received information that the two culprits had recently returned to their hometown of Sialkot after they fled Hong Kong for Shenzhen through illegal channels," the source said.
It was unknown whether the two men were still in Pakistan, he added.
