(Reuters) - Toyota Motor Corp's (7203.T) Indian unit has temporarily closed its two plants where some workers had stopped production lines to protest a delay in salary hikes after 10 months of negotiations.

The factories near Bangalore are Toyota Motor's only vehicle plants in the world's sixth-biggest auto market, where the Japanese manufacturer generates just a sliver of global sales.

Their closure raises the spectre of labour unrest at Indian car plants in recent years, including a 2012 dispute at Suzuki Motor Corp (7269.T) unit Maruti Suzuki India Ltd (MRTI.NS). A riot left one person dead and over 100 injured, and resulted in a $250 million month-long production loss.
