Kaitlyn Granado , 24 , was arrested on Monday amid claims she had sex with pupil , 15 , in her car on consecutive nights in January . A Texas math teacher has been accused of having sex with an underage pupil from a Texas high school a month after she was arrested for letting another teenage touch her breasts . Kaitlyn Granado , 24 , a teacher at MacArthur High School in Irving , was first arrested on March 19 for having an inappropriate relationship with a 15-year-old student , and was released on bail . Now she has been arrested again after another pupil , also aged 15 , also accused Granado of having sex with him on two consecutive nights in January this year . According to the affidavit , seen by the Star-Telegram , the teen claims the sexual relationship took place in her car late at night on January 18 and 19 across the road from another school in Dallas . The abuse came to light after a school police officer learned of a possible relationship between Granado and one of the boys last month . She was arrested on March 19 , and in a police interview she admitted kissing the pupil and allowing him to touch her breasts in April the previous year , according to the Dallas Morning News . She was subsequently suspended from teaching and put on administrative leave by school officials . At the time , detectives said they did n't think she had been in a relationship with any other pupils , but just days later , on March 24 , officers quizzed a second boy about a possible relationship with her . A spokesman for the police department said : 'There was some discussion , some rumoring , there may have been a second person involved . 'That information came from within the school , and it turned out to be true . ' Granado , who is a maths teacher at MacArthur High School in Irving , Texas ( pictured ) , was also arrested last month when she admitted kissing another boy , also 15 , and lettin him touch her breasts . Granado was booked into Irving County Jail for the second time on Monday , and released after posting a $ 50,000 bail . It is not known how Granado intends to plead to the second set of charges against her . A spokesman for Irving school district said : 'While privacy laws prevent us from sharing specific details , we can reassure our families that we took immediate and appropriate action . 'Being on administrative leave prevents her from working with students and being present on any Irving ISD property . '
