The Bombay High Court on Monday quashed the conviction of 12 persons in the 2006 Mumbai train blasts case and acquitted them, noting the prosecution has "utterly failed" to prove the case against them, reported news agency PTI.

The judgment comes 19 years after the terror attack that shook the city's Western Railway network, resulting in the loss of over 180 lives and leaving several others injured.

A special bench of Justices Anil Kilor and Shyam Chandak said the evidence relied on by the prosecution was not conclusive to convict the accused persons, reported PTI.
