Irish nanny 'violently assaulted' baby daughter of British entrepreneur Prosecutors said doctors also found evidence that Rehma was recovering from existing fractures to her left arm and leg when she died. Mrs McCarthy Brady, of nearby Quincy, denied all charges in a hearing at Cambridge district court, where she hid from public view. Her lawyer, Melinda Thompson, said that she had "loved" Rehma, and claimed that the child had returned malnourished from trips with her parents to London and Pakistan. The nanny, who was previously arrested for alleged assault and was the subject of two restraining orders, was detained pending a court hearing next month. Bail was set at a $500,000 (£315,000) cash bond, with demands that she surrender her passport and be placed under house arrest with a GPS tracking device. Police said that she had been alone with Rehma from 9.30am on Jan 14, after Ms Siddiqui left the family's home in the affluent Boston suburb of Cambridge. Mr Sabir, 34, moved to the city from Britain for his postgraduate studies at Harvard University and Massachusetts Institute of Technology in 2008. His wife, who was born in Pakistan, works as a chartered financial analyst for an asset management firm in Boston. The 29-year-old graduated with a degree in science and engineering from New Jersey's Princeton University. Officers arrived at the couple's home shortly before 5pm on Jan 14, after receiving a 911 call from Mrs McCarthy Brady, who is originally from Co Cavan. Rehma, who was found to be unconscious, was taken to hospital, where she was treated for bleeding to her brain and eyes. She was declared dead two days later. Police discovered traces of blood on the pillow and blanket in her crib, and on discarded baby wipes, according to court documents. They also reported finding that a wall was damaged by "forceful contact" with the baby's changing table. There was no answer last night at Mr Sabir and Ms Siddiqui's rented condominium, which had received deliveries of flowers and condolence messages. Mr Sabir is the founder and president of MoMelan Technologies, which develops devices for carrying out skin grafts. He graduated from University College London with a degree in immunology before spending three years as an investment banker at JP Morgan. He also worked as a management consultant before studying for a master's degree in business in Massachusetts. US immigration officials said Mrs McCarthy Brady had outstayed a 90-day visa waiver in 2002. She is believed to have married Don McCarthy, a 38-year-old, Irish-born painter, last year. On Wednesday night Mrs McCarthy Brady's upstairs neighbour said that he knew "what she's capable of" based on the "anger that she would display" around the area. "I wouldn't leave my dog with her," Thomas Collins, a 46-year-old ironworker, told local television news. I wouldn't let her watch my dog.
