JERUSALEM — The Israeli police briefly detained a leader of a Jewish women’s rights group on Tuesday for bringing a Torah scroll to the Western Wall, signaling a resumption of the battle over rituals at the holy site here.

Lesley Sachs, the executive director of Women of the Wall, was detained as she exited the Western Wall plaza Tuesday after prayers to mark the start of a new month in the Hebrew calendar. Women of the Wall is a feminist group of Jews that has fought for 27 years for equal prayer rights with the male-dominated religious establishment that has enforced strictly Orthodox and traditional practice at the site.

A police spokeswoman said that Ms. Sachs was taken in for questioning after a complaint was lodged against her, and that she was released within a few hours.

The rancor over the wall has caused deep discord between the Israeli authorities and Jewish leaders abroad, and tensions are rising again as a government plan approved earlier this year to resolve the issue has stalled.
