Police in India have arrested the owner of a hospital in connection with a fire that killed 20 patients.
Manoj Nayak, chairman of the private SUM hospital in Orissa state, presented himself at a police station late on Wednesday.
Four others, including a doctor, have been held over the blaze.
The fire swept through the dialysis and intensive care units on Monday. It was believed to have been caused by an electrical fault.
Orissa police chief Kunwar Brajesh Singh said Mr Nayak is the "main trustee of the hospital. He is the man behind the show, he was running the hospital".
"He came to the police station. After his surrender, he was interrogated and he has been arrested," he told the Times Now TV network.
Police said the hospital's medical superintendent, fire safety officer and two electrical division workers had been detained.
They have been charged with "homicide not amounting to murder" and negligence, police commissioner Yogesh Khurania told reporters.
