MANILA - Former transportation secretary Joseph Emilio Aguinaldo Abaya on Monday faced another graft complaint over the P3.8-billion maintenance contract for the MRT-3, this time from left-wing groups.

The complainants, led by Bagong Alyansang Makabayan, alleged that the agreement with Busan Universal Rail was "anomalous and disadvantageous," said Bayan secretary general Renato Reyes.

"Sinisisi natin [ang kontrata] sa deterioration o pagsahol ng serbisyo at kalidad ng tren," Reyes told DZMM.

(We blame the contract for the deterioration of MRT services.)

The Department of Transportation last month terminated the government's contract with BURI and filed a graft complaint against Abaya and several other former officials.

Reyes said the private sector complaint against Abaya was "more comprehensive," backed by 52 boxes of annexes and evidence.

The MRT, which runs almost the entire length of EDSA, ferries half a million passengers on average every day.

Last Thursday, some 140 MRT passengers were evacuated after 2 train cars detached from each other. Two days earlier, a woman's right arm was severed when she fell onto the tracks at the MRT-Ayala Station after she felt dizzy.
