MOSCOW (Reuters) - Russia's Transneft pipeline monopoly said on Tuesday that four new suspects being investigated over a major oil contamination earlier this year were employees of its Transneft-Druzhba subsidiary, the Interfax news agency reported.

The four men are being held under house arrest on suspicion of damaging the pipeline, Transneft was cited as saying. Six other suspects were earlier accused over the oil contamination, Interfax reported.
