Majinder Singh Sirsa and Om Prakash Sharma were marshalled out after they kept interrupting a discussion on a resolution moved by Transport Minister Kailash Gahlot against the proposed fare hike.
After this, the other two BJP law-makers -- Jagdish Pradhan and Vijender Gupta -- walked out of the house.
The Aam Aadmi Party government has locked horns with the Delhi Metro Rail Corporation over the fare hike to be enforced from October 10 -- the second this year. The last hike was effected in May.
The resolution moved on Wednesday by Mr Gahlot urged the Ministry of Urban Development to "quickly and actively intervene" so that the proposed "unlawful and anti-people fare hike" be reversed in the interest of the common people and the environment.
Speaker Ram Niwas Goel ordered the removal of the law-makers saying that the discussion on the resolution was extremely important as fares were set to go up from Tuesday.
