HOUSTON — One of the two antiabortion activists indicted last month after making undercover videos about Planned Parenthood turned herself in Wednesday to Texas authorities.

Sandra Merritt appeared in a Houston courtroom and posted bond, which was reduced from $10,000 to $2,000. The other indicted activist, David Daleiden, was scheduled to turn himself in Thursday.

Both are charged with tampering with a governmental record, a felony. Daleiden also was indicted on a misdemeanor count related to purchasing human organs that carries up to a year in prison. Their attorneys have said the two activists plan to plead not guilty.

Harris County prosecutor Britni Cooper said Merritt can settle the case through pretrial diversion, a form of probation typically offered to nonviolent first-time offenders.

Merritt declined to comment Wednesday, but stood beside attorney Dan Cogdell as he criticized the prosecution.

‘‘The indictment is wrong-headed,’’ he said. ‘‘I don’t care if you’re prolife. I don’t care if you’re prochoice.’’

District Attorney Devon Anderson’s office initially launched the grand jury investigation to look into Planned Parenthood after the undercover videos claimed that the abortion provider illegally sold fetal tissue to make a profit.
