State Labour Commissioner Angela Bradstreet said RadarOnline endangered Nadya Suleman's newborns, Noah and Isaiah Suleman, by failing to get required state permits, videotaping the infants at hours and for periods of time banned by regulations, and failing to provide a monitor to oversee their welfare.

Ms Suleman had an exclusive contract with the Web site that permitted videotaping of the children, according to a copy of the agreement.

Chris Myers of RadarOnline said he hadn't seen the labour law citations and had no immediate comment. The site's executive vice president, David Perel, did not immediately return a phone call seeking comment.

Calls to Ms Suleman's lawyer, Jeff Czech, were not immediately returned. The citations name the Web site only.

The four violations deal with a single day, March 17, when the two infants were the first of Ms Suleman's octuplets to be brought to her home in La Habra, a Los Angeles suburb. They were greeted by a crush of photographers, neighbours and curious onlookers.

The citations carry penalties totalling as much as US$3,000 (S$4,387), but state officials stressed the investigation was continuing. It's possible other violations could follow targeting other days or other children Ms Suleman, an unemployed, divorced mother, gave birth to the octuplets nine weeks premature on Jan. 26.

She already had six children, ages 2 to 7. The births set off media frenzy, with public adoration soon turning to scorn with revelations that Ms Suleman was not working and had conceived all her children through in vitro fertilisation.

The octuplets spent their first weeks in the neonatal intensive care unit at Kaiser Permanente Bellflower Medical Centre.

Radar has posted more than 100 items about the octuplets mother to their site, many of which include video. The footage ranges widely, from her squabbles with her mother, to a trip to Disneyland with her daughter in tow, to her vow of celibacy and other details of her personal life. -- AP
