National Accountability Bureau (NAB) on Wednesday extended ongoing probe against alleged irregularities in multi-billion dollars Orange Line Train Project.

Sources privy to development stated that anti-graft watchdog had acquired record pertaining to awarding contracts. On the other hand, Shehbaz Sharif-led Punjab govt had refused to hand over record of key contracts to NAB.

Inside-aware revealed laws were either disregarded or revoked while contracts were given on basis of sheer nepotism.

Separate contracts were awarded for route or Orange Line Train and construction of roads.

Likewise, Punjab govt has refused to share details of accord sign with Chinese government with NAB.
