The Lokayukta (anti-corruption ombudsman) has taken suo motu (on its own) cognisance into the collapse of six of seven 'Saptarishi' idols at the 'Mahakal Lok' corridor in Madhya Pradesh’s Ujjain.
It has asked its technical wing to investigate the incident, the news agency PTI said.
It said Lokayukta has asked Ujjain Smart City authorities to submit the documents pertaining to the corridor before it on June 10.
The entire cost of the corridor is Rs 856 crore, including Rs 351 crore for the first phase.
The corridor, said to be one of the longest in the country, traverses the old Rudrasagar lake that has been revived as part of the redevelopment project around the Mahakaleshwar Temple, one of the 12 'jyotirlingas' in the country.
Measuring more than 900 metres in length, the corridor has around 108 aesthetically ornate pillars made of intricately-carved sandstones that depict the 'Anand Tandav Swaroop' a form of dance of Lord Shiva, 200 statues and murals.
The first phase of the Mahakal Lok corridor was inaugurated by Prime Minister Narendra Modi in October last year.
After the idols collapse incident on May 28, MP Congress chief Kamal Nath sought a probe into the "sub-standard construction", while senior party leader Arun Yadav slammed the BJP government, alleging its corruption was "not sparing even gods", it mentioned.
The BJP government in Madhya Pradesh has denied corruption charges levelled by the Congress and blamed gusty winds for the incident.
