Taipei prosecutors yesterday said they were investigating a father-daughter team on suspicion of adding methyl alcohol to gasoline at the gas station they operated.
The Heng Chia Gas Station on Wanfang Rd in Taipei City, formerly a CPC Corp, Taiwan station, was caught selling gasoline mixed with methyl alcohol to cut costs.

Prosecutors said the pair denied putting methyl alcohol into the station's gasoline tanks and accused CPC of providing them with substandard gasoline.
Prosecutors released the pair without bail, but said they would summon them again for questioning after more evidence has been collected.

The CPC has come under fire from the public over its slow reaction to these incidents.
